Bose 901 Speaker Restoration

I’ve posted up a new hack page detailing a the Bose 901 Speaker Restoration that I recently completed.

Bose 901 Series IV Speaker Restoration

Bose 901 Speaker Restoration

Last spring I happened to come across a set of old Bose 901s for sale in the marketplace of my local car club… At a price of $25 including the equalizer unit I couldn’t pass it up. I contacted the seller and met him the next day in Manchester to pick them up.

For those of you unfamiliar with the 901s they’re Bose’s Flagship Stereo speaker set and they’ve been essentially the most expensive set of Bose Stereo speakers you could buy for the last 50+ years. They still sell them today, although they’re on “Series VI” now. New a set of Series VI retails for around $1400. Honestly the design of the 901s has barely changed save for the electronics in the “equalizer” module. The cabinet design, drivers, and wiring in speakers themselves haven’t changed functionally since the Series III.

I’m not a huge fan of these speakers but I bought them because my Father is, I really have no need or room for a set of 901s in my house but I figured I could fix up these speakers and it would make a nice Gift at some point.

My father had a set of 901s (Series V I believe) a number of years back and loved them, I remember he always talked about getting a pair way before then, and he was extremely happy when he was able to finally afford a set. Though about 2 years ago he had to sell them. So you can understand why I wasted no time to pick up such a cheap set of easily restored 901s.

What I started with:

Being a Series IV (which sold new from 1978 through 1982) the cabinet style, though functionally identical the series VI (which was released in 1987 and has not changed since) does look quite dated in terms of the grill fabric and cabinet color.

Removing the Speaker Grills:

Obviously the first thing I did before I could attack the innards was take the original grills off.

Bose 901 Series IV Speaker Restoration - Grills

The front grills are held on with 6 staples, 3 down the left and right sides. They were somewhat difficult to spot. I’ve circled it in the above picture.

Bose 901 Series IV Speaker Restoration - Grills

I started by hammering a cheap screw driver under one of the staples to pop it out a little.

Bose 901 Series IV Speaker Restoration - Grills

I then used some vice grips to yank  the staple out completely.

Bose 901 Series IV Speaker Restoration - Grills

Once the first staple was removed I had enough room to get my hand behind it so I just ripped the rest of the grill off by hand.

Bose 901 Series IV Speaker Restoration - Grills

The front grill frame is made of particle board so the staples ripped right through it, but it doesn’t really matter because I wont be re-stapling it. Once the grill was off pulling out the rest of the old staples with the vice grips was easy.

The rear grill was simply attached with some tree-sap like glue, pulling it off by hand was a breeze.

Parts, Costs, and Planning:

Once the Grills were off I could get a good look at the drivers, time had not been kind to the foam surrounds. All of them were rotted, and some had fallen off of the drivers completely.

Looking closer at the drivers the cones, dust-caps, and voice coils all looked to be in great shape, it was just the foam surrounds that were decaying.

Parts Express sells kits to replace various components, you can buy dust-cap replacement kits, foam surround replacement kits, and if the drivers are so far gone you can even buy replacement drivers.

Bose 901 Series IV Speaker Restoration Parts Express Foam Surround Kit

The kits I needed run $35 a piece and I ordered 2 Bose foam surround repair kits (10 foam surrounds per kit) to replace the foam on all 18 drivers (yes 9 drivers per speaker, each driver is <1Ohm and they’re wired in series). There are other kits available elsewhere for less but I know and trust Parts Express having ordered many times from them in the past.

The only other thing I needed for this project was fabric. Parts Express also sells Speaker Grill fabric but I opted to find some locally. I discovered that my local JoAnn Fabric store sells “Speaker Grill Cloth” for $10 a yard. They were having a 40% off sale so I bought 3 yards for $18 since there are some other projects that I would like to have the fabric for.  Considering the width of the fabric you could easily get away with Just 1 yard for the 901s if you planned your cuts right.

Total cost of these speakers was ~$100 not counting disposables such as razor blades, hot glue, and sandpaper.

Driver Removal:

The first thing I did was remove all the drivers (3 bolts each requiring a 1/4″ socket).

I was somewhat shocked when I pulled out the first driver to discover that they use wire wrap for all the internal electrical connections.

Bose 901 Series IV Speaker Restoration - Wire Wrap Driver Connections

I’d never worked with wire wrap connections before. It seems most electronics had abanoned it before the 80s since the only arcade machines I’d ever seen use them were the extremely old pinball machines from the 50s. even those from the 60s and 70s had moved on to more modern connector techniques.  I also discovered that it was difficult to remove old wire wrap without fitiguing and breaking the wire.

Bose 901 Series IV Speaker Restoration - Wire Wrap Driver Connections

Since I don’t own a wire wrap tool, I decided that I wouldn’t worry about it and would rather just go with a spade style connector or soldered connections when I put the drivers back in. Based on what I’ve read elsewhere it sounds like the newer series 901s use soldered connections anyway.

To ensure I put everything back the way it should be I numbered each of the drivers and each of the mounting locations, I also labeled the wires in the cabinet to ensure I didn’t reinstall any of the driver’s backward.

While I was in there I decided to map out the internal wiring. A quick search on google turned up this diagram:

Bose 901 Wiring Diagram

The text listed with the image stated that it was the diagram for the Series II and Series III revisions, I would tend to believe it as it did not at all match the wiring I found inside my pair of Series IV speakers. I’d read that the Series IV through VI used similar wiring. Using the diagram above as a starting point I modified it to reflect the wiring found in my Series IV.

Bose 901 Wiring Diagram

The yellow wire at attaches to the #9 driver goes to the “*” terminal on the outside of the speaker. I’m not sure what this terminal is used for but the labels on the speaker cabinet state not to use it.

Driver Cleanup and Prep:

Before I can do anything with the drivers they need to be cleaned up. All of the old decaying foam surround material needs to be removed and the surfaces cleaned and ready to glue on the new foam.

First thing I did is pull off as much of the rotted foam I could with my hands. Once the bulk was removed I used a razor to cut off as much of the old glued foam as I could,  a fresh blade with sharp edge and the right angle and you can strip it off without much issue. I went over the glue foam on the cone 2 or 3 times taking off progressively more each time, as a paper cone it is extremely delicate so taking your time is preferred.

Bose 901 Series IV Speaker Restoration

Next I used a small screw driver to scrape the old glue off the basket.

Bose 901 Series IV Speaker Restoration

Once all the material had been removed I rubbed my finger over the foam on the cone to loosen up and brush off any dust or small particles that remain. Then I went over the whole thing with compressed air to remove any particles left, taking caution to make sure there isn’t anything under the cone.

Finally I went over the basket surface with isopropyl alcohol to make sure it’s completely clean, I don’t do this on the basket surface as it could damage the cone.

Bose 901 Series IV Speaker Restoration

Now I have a nice clean driver ready to receive a new foam surround.

Bose 901 Series IV Speaker Restoration

Installing the Foam Surrounds:

I started by placing a bead along the edge of the cone as well as one along the inside edge of the foam surround.

Bose 901 Series IV Speaker Restoration

I used the swap to spread it out a bit, I did a little more after the above picture was taken, you want a nice thin, even layer over the whole area to be glued.

You should let the glue “set” for 5-7 minutes before attempting to stick the two sides together, it turns clear when it’s ready. Most of the time I found it was easier to know when it was ready by the clarity of the glue rather than some arbitrary amount of time.

Centering the foam surround is CRITICAL. the cone sticks up past the basket slightly, so I placed the ring, then pushed the cone down slightly and made sure that the ring is centered on the basket, then when I relieved pressure on the cone it would center itself.

Bose 901 Series IV Speaker Restoration

After that I went around the edge of the cone applying pressure to ensure good adhesion.

Only the center part of the foam is glued at this point. It needs to setup for at least an hour before the outer edge of the surround could be glued. To be on the safe side I let them sit over-night before continuing.

Once the glue has dried on the inner portion of the surround I could begin gluing the outer edge.

I started the outer edge by first running a bead along the flat surface of the basket.

Bose 901 Series IV Speaker Restoration

Then I put a small amount of glue under the edge of the foam surround, this is a pain since you have to peal the foam up with your hands and spread the glue over a small section at a time until you’ve gone around the entire edge.  This is also why you need to let the glue on the inner edge completely dry before attempting the outer edge; the stress of pealing up the foam could compromise the adhesion on the inner edge.

Bose 901 Series IV Speaker Restoration

Once the glue has been placed I used one of the included swabs around the parameter smoothing and evening out the glue on both surfaces.

Bose 901 Series IV Speaker Restoration

Like the inner edge, I let this set for 5-7 minutes before affixing both surfaces, they wont touch since the cone naturally sits up higher than the basket.

Centering the outer edge is perhaps even more important than centering the inner edge. The reason being is that any mistakes made on the inner edge can be corrected with the outer edge, so there is no room for error.  If not centered properly the cone will not be able to move up and down smoothly and the sound quality with be severely diminished.

To ensure it’s centered I used a bottle of water, with just enough water to push the cone down without crushing it. The water also ensures that it’s being pushed straight down and perfectly centered. My kit didn’t come with any, but some other kits include shims to help ensure that the cone is properly centered during this step.

Bose 901 Series IV Speaker Restoration

Again I go around the parameter applying pressure until it’s affixed well. I leave the bottle on the cone for a minute or two to let it settle to ensure that the foam doesn’t pop back up.

Bose 901 Series IV Speaker Restoration

The glue should dry for at least an hour before you reinstall them. Keeping them on their backs while they dry will help ensure good adhesion.

Reinstalling the Drivers:

I looked into various spade connectors that I could use to hook the wires up to the drivers but alas I couldn’t find any that were worth using. Without the proper tool to do wire wrapping I ultimately decided to just solder them back together, I don’t really plan on taking these things apart ever again so I might as well. Reading around I get the impression that the Series V and VI use soldered connections on the drivers anyway.

I started by ensuring I had straight/stripped wire ready on each connection, I used a slight bit of sand paper to take the dust and coating off the wires, they have a coating to prevent oxidation but it also hinders soldering (since it was designed for wire wrapping) just a light sanding is all that was needed to ensure that the solder will stick well.

Bose 901 Series IV Speaker Restoration - Soldering

I did the same on the drivers, only I used a screw driver to scrape it off since it was much thicker and heavier on the wire posts than on the wires themselves.

Bose 901 Series IV Speaker Restoration - Soldering

I tinned both the posts on the drivers and the wires.

Bose 901 Series IV Speaker Restoration - Soldering

Once everything was tinned I soldered each of the driver’s connections, tore off my wire markers (I wouldn’t want them buzzing inside the speaker once it was all back together).

Bose 901 Series IV Speaker Restoration - Soldering

After soldering each driver I bolted them back into the cabinet before starting to solder the next. I also re-used the original foam isolator that goes between the driver and the enclosure, these were still good and they keep the drivers from buzzing or rapping against the enclosure.

Since the wires were short I did the bottom row of speakers first, then flipped the enclosure upside down and did the other row, it saved me a 3rd hand.

Once the speaker has all the drivers back in place it is functionally restored.

At this point I tested the speakers. They sounded great but I did notice that one of the terminals was lose, so I pulled out the nearest driver so I could tighten the screw on the inside.

Grill Cleaning and Prep:

Now that the speakers were functionally restored, all that was left was to make them look a little more up to date. I decided that the wood coloring wasn’t all that bad, and while the cabinets had some scuff and scratches my wood finishing abilities have something to be desired. In the end the only updating I would do is the grill cloth, replacing the ulgy Tweed with some new, more modern black acoustic fabric.

Before I could do anything though I had to strip down the old grills to their bare frames.

I started by removing the push pin badges from the front grills.

Bose 901 Series IV Restoration - Grill Badge

The fabric on the front grills was easy to remove just pulled it off with my hands and spayed it with some compressed air and they were ready for new fabric.

Bose 901 Series IV Restoration - Grill

The rear grills needed a little more work before they would be ready for fabric though.  I used a razor blade to separate the plastic port hole trim pieces from the grill, then pulled the material off by hand just like the front, then I used a razor to clean up all the large glue bumps left around the port hole areas.

Bose 901 Series IV Restoration - Grill

Unfortunately there were little bits of tree-sap glue as well as tweed “fur” stuck all over the grill frame to the residual contact cement.  To get rid of this I took a block sander and sanded it down to remove all that. Then I dusted it with a damp rag then once dry I went over it with compressed air for a nice clean and smooth grill frame.

Grill Re-Upholstering:

Now that the front and rear frames were prepped they were ready to be reupholstered. I’m not much of a fabric person so I just did what made sense to me, overall I was pleased with the outcome though.

I started with the front grill. I laid the grill down on top of my fabric and cut around it so the fabric stuck out roughly an inch around the parameter of the frame.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

Normally acoustic fabric is installed using a spay on contact cement.  I really hate working with that stuff, and acoustic fabric is stretchy in all directions, so I decided I would just work my way around with some hot glue. It worked exceptionally well. After each tack I’d check to ensure I wasn’t introducing any wrinkles on the other side.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

After I was done gluing I went around and trimmed off all the excess material.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

Finally, I put the badge back in place though the original hole to complete the front grill.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

For the rear grilsl I started by cutting, gluing, and trimming the fabric just like I did on the front grills.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

Once the fabric was glued and trimmed I cut an X one of the port hole areas with a sharp razor.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

I then pressed the port hole trim through, checked for wrinkles, and trimmed up the excess fabric.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

After that I hot glued the trim ring in place (which also helped secure the fabric around the ring as well). Following that procedure for the rest of the port hole openings the rear grills look nice and neat when done.

Bose 901 Series IV Speaker Restoration - Grill Reupholstering

Once all 4 grills had be reupholstered I hot glued them back onto the enclosure. I figured this would be more visually appealing than re-stapling the front or finding some kind of replacement glue for the rear. Hot glue holds securely but can also be easily pulled off if need be.

The front grills were tacked in six spots where the staples used to be.

The rear grills were tacked in ten spots where the “tree-sap” glue used to be.

The Results:

Overall I’m quite happy with the results, with a few days worth of work and relatively little money spent I ended up with a nice looking and nice sounding set of classic stereo speakers. Hopefully they’ll seem some good use in years to come.

Oil Pan

More work got done over the weekend, Oil oil pan was pulled off.

GM apparently decided it was a good idea to rivet the gasket to the oil pan so those had to be drilled off.

however now I’m stuck on this… this is the old dip-stick hole which needs to be plugged. On newer GM vehicles they tap it and use a 1/8 NPT pipe plug. Joe and I drove around to every store in Tilton and Lowes was the only place that sold the tap, no one sold the plug. so I ordered the plug off of ebay … after shipping I’m paying essentially $5 for a screw… waiting on that

dip-stick_hole

old cross member was pulled out too, here it is next to the new one. you can see the cut out center cross section and the engine mount humps are at a different angle (the new one is a modified RB cross member).

x-member

the new cross member is back in the car but the steering rack isn’t bolted back in yet, I decided to order some steering rack bushings while it’s off so I’m waiting for those.

I also got into today a bracket for the Clutch Master. This thing is f-ing slick… I don’t know why I’m so excited about this little part but I am. I guess I just think it’s cool that a custom part designed by some random guy looks so pro, and it was dirt cheap too, $25 shipped. I got it from Rigid over on silviav8.

I got my long-tube headers in too, I didn’t get a chance to snap any picture of them though…

LS1 and S14 Harness Integration

A minor update on the LS1 swap. I finished removing the LS1 engine harness as well as some other unnecessary stuff. I also got some new tools as well as a proper engine stand (though the motor isn’t up on it yet). The Fujii boys also stopped by briefly last weekend and pulled the starter motor, the Auto flywheel and the headders off… looks like a totally different motor now.

Next time I have a 2nd set of hands to help me I’ll throw it up on the stand (I don’t trust my ghetto-ass cherry picker to do it myself) then I can swap out the oil pan then drop it back down and throw on the new LS6 clutch… yummy

I also spent some time pulling off a bunch of unneeded brackets and other crap from the transmission and cleaned it up a bit while I was at it and mocked up the new transmission cross member.

My main attention now will be on the harness, I dumped all of the harnesses that I need to tie together into a big box and brought it into my office… looks kind of overwhelming.

LS1 engine and tramssion Harness and S14 Engine Control Harness

Though spreading the KA harness out on the floor so you can see the whole thing all at once it doesn’t look so bad. Trimming off the KA bits will be the easy part… the hard part will be weeding through what is and isn’t needed on the LS1 harness.

Marantz Fixed

After scratching my head over the broken Marantz I finally determined a cause of death.

Some friendly folks at diyaudio.com brought to my attention that the failure I experienced could have been caused if the speaker outputs were crossed, thus overloading the Darrington transistors.

Thinking back to the day it happened I had pulled out the receiver earlier in the day to hook up a Sega Saturn (which only produces stereo sound. eg: no center channel used) after playing that for a while the system was shut off. We returned hours later intending to play Xbox 360 (which is setup for surround sound. eg: center channel is used) and when the system was switched to the surround input by the harmony remote moments after being powered on is when it sparked an popped.

The crossed speaker wire theory fits because a few stray strands could have easily been grounded to the chassis or the other side of the speaker output when I pulled it out for use with the Saturn and then that channel wasn’t used until hours later when it popped.

Also there is no indication of any other component in the unit failing. Having 6 identical amplification circuits I was able to test  the dead circuit agains the working ones and aside from the part that blew everything checked out ok.

After researching parts I found that the transistor that blew is discontinued… replacing it would cost me $10 worth of parts + $8 shipping. that and I was a bit worried that maybe I was missing something and the next time I powered it up it would pop.

I decided to simply reconfigure the amp internally. Since it’s a 6.1 Receiver and I never use the Rear Center channel I basically just re-pinned the amp connector to use the rear center channel amp for the Front Center channel. then I removed a few other key component from the original Front Center Channel to ensure that it wouldn’t receiver power.

After putting it back together and testing it works great… just as it always has.

Since I’ve got a new receiver now I’ll be selling off the old one… I’ve got all of the original accessories, manual, even the original box it came in. I figure considering it’s age and what happened I’d probably let it go for $120 or so.

Marantz SR6200 Marantz SR6200 Marantz SR6200

I’m also going to get rid of the two Component Video/Optical switches I’ve got as well as the HDMI switch I’ve got and I’m thinking about selling off my PS1 and Gamecube as well since I don’t use either anymore.

Crash and Burn… Litterally

So Wednesday night my desktop locked up, which was quite unusual, then it was running slow so I shut it down and it never came back up. It wasn’t until Thursday night that I was able to determine that the Windows Partition of my primary hard drive had crashed. Somehow the formatting had become currupted such that the PC could see the drive but had no idea what was on it, or how things were stored.

My brother had dropped off his PC, which wasn’t working right, so I spent time fixing his (which turned out to be driver incompatability issues… this is the third time this year where I’ve seen windows update upgrade drivers to new versions that don’t work… yay). Once that was squared away I got to work on building another PC from scratch so that I could not only get back online but use it as a tool to help recover (or at least determine the extent of damage to) my crashed hard drive.

I spent most of my day on Saturday working on this… Saturday night however my Marantz SR6200 decided to catch fire… this was turning out to be an expensive weekend. Thankfully shortly after the fire I was able to finish diagnostics on the crahsed hard drive and repaired the borked formatting…

Saturday night this is how my office looked:

My Desk Saturday Night

From left to right: an Xbox I just finished fixing, my post fire SR6200, the PC I threw together, and my desktop with it’s hard drives pulled out the side.

The desktop is running well enough to get my files backedup but in general it’s acting like it’s got brain damage, some programs just flat out wont run, others will run for a while and then just stop working, and it’s a whole lot slower than it was before. I’ve got everything backed up now and a new hard drive on order. In the mean time I’m using the piece-built PC, it’s only a P3 700MHz but it gets the job done.

While finding the source of the fire in the Marantz wasn’t easy, it became pretty clear once I unbolted the amplifier board…

Burnt out Marantz SR6200 Burnt out Marantz SR6200 Burnt out Marantz SR6200 Burnt out Marantz SR6200

It looks like a major transistor failed. The part was an SAP16 NPN 1413 Darlington transistor made by Sanken Electric. I found replacements online for $2 a piece. Hopefully nothing else was damaged and the receiver will be back up and running with a fresh replacement.

Even if I do get it running again I’ll probably just sell it and buy a new Receiver. I’ve been shopping around online and a comparable replacement is in the realm of $1200 new… that’s with similar power and audio quality in addition to new features like support for HDMI 1.3a and HD audio formats.

I’m looking heavily at the Marantz SR6003 or SR7002 to replace this receiver, if anyone has any suggestions let me know.

Evapo-Rust Mini Review

So I had these bolts and eccentric washers that I took off my car and replaced and really I didn’t even need to. The old ones were coated in surface rust so I decided to try some stuff to take it off.

I had read a few raving reviews about Evapo-Rust and seen some videos so I decided to give it a shot. The stuff looks like anti-freeze but it feels slippery like dish-soap on your fingers. It’s pretty expensive too this bottle cost just under $9 and it was barely enough to do the hardware I was cleaning. Though it’s supposedly reusable so I dumped it back in the bottle once I was done.

Here’s a picture of my hardware beforeI did anything.

 Evaorust Test Evaporust Test

Notice there is both surface rust as wella as this thick black stuff. That thick black stuff is rubberized undercoating because the previous owner of the car had it coated to prevent rusting and it got on some of the bolts. It looks really nasty but it doesn’t harm anything. Apparently Evapo-Rust doesn’t harm plastic or rubber so I went into this assuming that it would leave theundercoating stuff (which kind of sucks becaus it looks ugly).

I dumped the whole bottle of of the stuff in the bottom of a cut-up water jug and just dumped all my hardware in there. Supposidly it does it’s work in a matter of minutes but I was on my way out so i just left it for the night.

Evaporust Test

The next morning after rincing off the hardware it looked like this:

Evaporust Test  Evaporust Test

 Some patches of rust still remained but it was mostly cosmetic as the parts were all smooth to the touch. As suspected the undercoated parts were still narly. I decided to try a 2nd application to see if it could get rid of the rest of the crap to make them completely clean.

 Evaporust Test Evaporust Test

 I’m pretty happy with the outcome, if I want to remove the undercoated parts I’ll have to use paint stripper or a wire brush but on a whole the Evapo-Rust did it’s job. $9 might be a bit much but considering that all of this hardware NEW from Nissan cost nearly $100 to replace, I’m fairly certain that next time I take off some bolts I’ll clean them with this stuff before deciding to replace them. At least now the parts are clean enough that I’ll be able more easily sell them and recoup some of the money I spent on the new parts.

Refinish Restorer

After getting harassed by a co-worker for having ugly faded plastic cladding on my Vehicross, I finally got around to trying out the Refinish Restorer product I imported from Germany. I am so incredibly happy with the results, you have no idea.

Cleaning up the Vehicross

So yesterday I registered, the Vehicross, after which I had the oil changed with a full synthetic and had the coolant flushed and replaced, and changed the air filter.

Today I spent some time cleaning up the cloudy headlights…
