I enjoy your repairs. In my repairs, I see this type of thing a lot. Why not have three shoulders to hold that piece instead of just the one or simply make the base piece out of better material? At the price point of Bose equipment you'd think they could afford a few more pennies worth of material. I call it "planned obsolescence". Nice find and nice fix.
I worked on many 8 track players. They used elevation cams to raise and lower the tape head to play different tracks. They rarely gave trouble. Bose should have used that design. Only trouble I had with 8 tracks was a simple azimuth adjustment when they ran thousands of hours
the noise of that cd mechanism, sounds like cheap rubbish, would do my head in. I know it's not cheap as it is Bose.. over priced junk. I never want a Bose music system. ever. but I like your videos, they chill me out.
It's not only bose unfortunately. We are reaching the end of a technology. It the same thing that happened to cassette players, gone are the days of closed loop direct drive double cabestan soft touch mechanisms. Only the basic shitty, dirt cheap chinesium mechanisms survived and that is what you find in all the cassette players currently on the market. The CD technology has reached that point. 80% of the consumer gear that has a cd player will have the same mechanism with minor variations. I've seen cd players priced at 1k dollars that use the same mechanism as a 50 dollar radio/cd player. I miss the days of cast metal mechanism chasis, and overbuilt quality, just look at a kenwood dp 1100sg built thirty years ago. Heavy as hell, and built to send to the moon and back.
Awesome video with fantastic macro-closeups, so important in presenting what you're showing us. Thanks a million.... Would you be willing to tell us what model video camera you are using please?
Hi. Teacher. I am your fan and i learnt so much from you.thanks. i have a SHARP dvd recorder . Its power's lead has a magnetic box . It has knobs and i could remove magnet box and release wires like other set which they haven't this box. If i remove it , will it effect to functionary of the set ? Could you please answer me. Thanks
I have the same unit, the fault with it is that both laser units don't spin up. The bottom laser caddy units look to be out of wack like yours. Why do you think both don't spin
Great job. I just learned about JB weld, its great stuff. That shorting trace to protect the laser, is it not hard to solder to that film without melting it?
I've got one of the acoustic wave 5 CD changers on my bench took all the visible screws out and for the life of me I can't get the top off have any experience with them?
That's a great repair job. Really a puzzle to take apart and get back together again. Do You use the video and photo's when You reassemble it, or are you able to do it all at first try just from memory?
Greetings from the UK, can you tell me, your little blue handled precision screwdriver. Where can I get something like that? Is it one you have made yourself or can I get one from my hardware store? Thanks for all the work you share with us. I really enjoy your skillful workmanship, Lee.
Hi, i got this portable black and white TV which i saw has a blow capacitor and resistor. What i want to know is do i replace it or do i have to troubleshoot as to why it blew? the TV still plays with those blown parts and uses a separate dc 12v power adapter thought. Thanks so much...hope it's something small.
As i see this Video, i remember the Pink Floyd Song " Learning to fly"...... belive me this mechanisem on my bench and the mimic will fly..... out of the Window...... :-)
No, afaik nobody except bose ss they won't sell any replacement parts. You send it in and they send you a replacement for a fee as high as buying a new one.
Yes i think JB weld is the best, just a question is it neccesary for the jumper even though working on an antistatic mat as some laser diodes its not visible like that
They all have a short pad. This one has the one I shorted and another one on the strap that leads to the laser head unit. Some have it on the PCB with the laser diode but they all have it and yes you need to do it even on anti static mat. Just exposed to the air charges can build on the copper traces and kill the diode. They are one of the most sensitive devices out there in terms of esd.
If they don’t stock the audio harness, I would go with a mini stereo cable and jack modification. At least there will be no center pin to break off. Much better design
Thank you so much for posting this! Just fixed a completely dead 3 CD changer using this and your other video (ruclips.net/video/ghHJc-t8byo/видео.html). No parts needed, just some cleaning and adjustments...Absolutely perfect now! Thank you, thank you!!!
I don't have one and even I did where would I get the plans to make one. I know someone that has one and about the only parts he has been suscesfull in printing out that are useful is new battery compartment lids for the remote controls his kids break. He has had his printer for a few years too. Not as easy as you make it sound. These are precision parts and this has the screw threads in it but keep it up because it shows everyone that you have no clue. I should also point out that not only do j not have a 3d printer I have no interest in getting one. I have had 2 offered to me for free to review and I declined both. I have zero interest in learning a cad program either. I have had my friend with the printer attempt to make me parts and he has had no suscess making gears that actually work. About the only thing he has had any luck at is printing little models and figures using plans he downloaded.
@@12voltvids - I have 2 3D (FDM) printers and I agree that trying to make gears with them is a pain in the butt. Gears need to be printed from material like nylon which is expensive, absorbs moisture and is hard to print. I have not tried it but I think that a better path to (homemade manufacturing)success would be to use a SLA (laser) 3D printer, use that to make a mould and then cast the new gear.. maybe using JB Weld :)- Either way its a long arduous process to get a simple gear (or in that machines case it would have been a linear drive nut) re-manufactured. If the owner really loves it then sourcing a donor machine would have bee a good fallback to get spares... but you already know that... Good job on getting that beast back together. Cheers, - Eddy
im having trouble aligning tray on all the 3 corners. how did you balance the tray correcting inside so it loads and plays the disc correctly.. I keep trying to adjust each of the three elevator screw to get close to playing with no noise then I lose the blanace again. im just curious to know if you know where the correct resting position is
This is much more difficult that it seems in the video. There is a sweet spot where it goes up and down and touches the bottom at exactly the same time on each side. There was much cursing initially when I started this and I would be very happy never to see another one.
Would you like to attempt to do this one? I can get it working if I push my finger one it but just can’t get the alignment just perfect enough so at this point I’d rather pay someone todo it as long as it’s not to bad
Hey been following the channel for years now I live in Vancouver but reason I’m making a comment is because I have an Xbox one S with a faulty HDMI port and me personally I could fix it but would make an interesting video on ur channel of course would pay for your time and repair If you’re interested shoot me a reply
There is no way I'd have had the patience for that, I'd have slung that thing up against the wall just as hard as I could. Engineers should be required to repair silly items such as these & many others for a full 6 months, daily before they could pass to design anything. That along with a report of how they would improve it, what, where & why. Also they'd have to be correct before passing. That was a waste on what could have been a good build, design.
A Three Dog Night - Its not the engineer making the decision to lowball the cost. These things are designed to a *given* budget, with the full intention to _not_ provide long-term support. A total 360 from 30 years ago when the focus was on good design practices, sometimes with a focus on repair-ability. This manufacturing design goal (cheaper, faster, crappier) is often referred to as _the race to the bottom_ - Eddy
We need a camera set up like yours to film repairs I just take photos I have another 2 laptops to strip , all mine now Emmmm Alcohol not recommended here lol
That is nothing short of amazing - how you discovered that crappy little plastic leg broken off and recognized it as the source of failure !! And - as I was watching you dis-assemble the transport I said to myself - "He'll never get this back together the same way" !! So I have a question. When reassembling it - how many times did you have to refer back to the video you made? laugh !!
Usually I don't have to look back at it. This one I looked back once to check the position of the 3 springs that hold the top clamp, but that is why I recommend recording the disassembly especially with something complex.
Is this really necessary? Does it add anything of value outside of the few kilobytes on RUclips's servers. If this is your pinnacle accomplishment in life that you're taking such pride in, I suggest you improve your life.

If it's Bose, it's definitely going to be a challenge, to try and repair the most simplest thing...lol
Pain in the ass these things are. Take something simple and complicate it.
Just try getting parts for them. None available but you can send them the unit and they will send you another one.
Expensive as their products are, they should replace it with no problem...lol
@@12voltvids They will send you another one because they can't fix them. I think MIT own's the company now.
@@rwj777 Complicated expensive Bose junk.
It's like one of those God damn 3D puzzles.
That's a nice work, but i believe if apply some gear grease it will be more quiet? 😉

Absolutely horrid arent they? the pioneer 6 disc cartridge changers were just as bad, they scratch the crap out of your cd's

The only good changers were the 5 disk units like SOny had, and the juke box type. They actually perform very well.

Sounded horrible. Glad you was able to eradicate the problem!!
You are like a surgeon!
All those mechanical units make noise like that.
Love Bose, mine is well over a decade old and sounds great.
Good old JB Weld to the rescue! 🥰
Excellent repair on a difficult mechanical fault.
I bought one of these today. The top parts works fine but the bottom three disc changer will not load the cd's. It does lite up when powered up.
Could you repair two Bose media centers?
I have the same unit, the fault with it is that both laser units don't spin up. The bottom laser caddy units look to be out of wack like yours. Why do you think both don't spin
Great job. I just learned about JB weld, its great stuff. That shorting trace to protect the laser, is it not hard to solder to that film without melting it?
will one of those changers work with the new IV system?
I've got one of the acoustic wave 5 CD changers on my bench took all the visible screws out and for the life of me I can't get the top off have any experience with them?
From an engineering point of view the worm drive nut is supposed to be able to move laterally to allow for eccentricity in the worm drive shaft.
That's a great repair job.

Jb weld. It is a 2 part epoxy with metal fillings for strength.
@@12voltvids thank you so much
They most likely don’t stock the gear. They will sell you a complete mechanism if you’re lucky. It will be very expensive because it’s Bose
