What I like about this air filter from IKEA, beyond being cheap to run and such. Is the fact, the filter input is Rectangular. So you can easily 'retrofit' other types of HEPA filters into it, if you want.

Great clip. Thank you for making me a professional belt replaceman and save my cd player

Thanks for sharing all this - I’m going to have to do exactly this. Mine is having the same problem. I have already received the relay (bought 2 just in case) Here we go…. Deeply appreciated.

did you ever manage to get this powered by the snapmaker?

It looks like SRM 1's circuitry is almost the same wth my SRM 717 except it has 2 x 4 power transistors.

Thanks for your video. I've problem with my SRM 717. The sound is weak. Do you know the problem? Ive checked the PSU. At the beginning its 2 one Watt power resistors' values change alot (i believe due to heat). I've checked the voltage. It's ok now. Same also with two 0.5 small power R which i thought on the final power transistors but the sound still weak. Do you the problem? Do you also have the schematic ? Thanks.

Thanks a lot ! Although I have been restoring v-fet amps for many years, I still learned some things. And yes, the way you have done this one is the extreme version of a restoration ;-). For anyone who tends to save some money on the relay: change it! The riveted plastic holding bar of the fingers will crack over time! I have done dozens of 4650's and others. At least half of them have a broken relay when they come in. And although your power caps still seem to be fine, capacitance wise, I see many who have less than 50% of their original capacitance left.

Bardzo dobry wzmacniacz, choć uważam że AU-9500 gra zdecydowanie lepiej ma bardziej naturalne brzmienie. Poza tym jeszcze lepsze granie można mieć z AU-70 czy 1000A

Holy crap this is the best shit I have found in a WHILE

What I did for a DIY solder fume extractor is use one of those old DELL/HP 20CM thick fans, with a DIY frame. its loud AF but it can even suck away air from 50CM away

Why don't input circuits need series resistors for protection? Won't they burn the amplifier?

Followed along and repaired mine. Thanks! It saved me a ton of time

They're 100V did you convert them to 115//120 V?

I was wondering how to clean up and repaste the transistors and your video helped alot, so thanks!

Very cool scanner and glad there are people appreciating and restoring such tech! Did you also clean the glass from underneath? Could not see it in the video :)

Surprised it had anything else than some plastic lens, used one of these in school and it was just as bad as any epson flatbed.. for the price i would have thought they could have managed to make something even half decent. It even has an actual focusing system, i remember trying to test its focusing and the results were just the same mush no matter what you did.

Tremendous. I enjoyed your practical approach. Especially in regard to debunking some myths (such as the need for an analog oscilloscope). Hats off to you for developing an understanding and sharing it so clearly. Liked and subscribed!

I have this CD player, I love the tubes' sound... Nice review!

great job man.practice soldering some more in ur free time

Xraytonyb worked on one of these and gave up on it. Maybe he needs to send it to you.

Amazing work! Congrats! I know this takes a lot of time for you already, but seeing measurements, and having some explanations why parts or bad or such info would help us learn more :)

what a nightmare ,you repairers have some balls

Long Vid the better 👍👍

He pulls the door cover off but doesn't explain how it's done. If been fighting with mine and cant remove it. Afraid it will break.

Nice flashlight

Anyone got the file for the 3D print of the gear? I would be glad to get that.

Anyone who got the file for the 3D print of the gear? I realy need that.

Really helpful, thanks.

Hi, for the bias adjustment did the 2 legs of the red goes to one meter and the 2 legs of the blue goes to the other meter OR one blue and red goes to one meter and the other red+BLUE to the other meter? If so what is the polarity? Thank you

Hi, how did you clean the pins on the power supply? What tool did you use?

I really enjoyed to see your videos. I have 2 questions 1. I don't understand is the blue and red bias wiring for the meters. Can you please explain how those wire are going to the meters. 2. the DC offset between hot and cold on both channels on my amp is 0V but on both channels there's 1.4V between hot/cold to the ground. What is the problem? It's too high. I will really appreciate your help. It will be very helpful. Thanks.

rebuild, Rebuild, REBUILD 🎉

Dude. Loved the video!

restore pls

half way through the close up shots of the burnt out channel I swear I saw luke skywalker flying his x-wing around the scorched laser cannon 😂 it looks like the Death Star in there Gold Leader…

A bother needs a thermal camera! :P

I made a similair mistake getting a Yamaha TC800-GL

Part it out or sell as is.

X ray tony b did one of those on his channel. What a piece of poo.

Sweet channel mate! You should definitely try and restore this. Very special piece of audio gear in my opinion, looks pretty cool as well.

who would not want to see its restoration? It is unique, and the more crazy work it needs, the better for the viewers :) I think you need to learn about youtube and your viewers, haha :)

Hi, This one wants to live again a happy life.... As you see how beaten up it is now, it still works... 🤩 And it screams: help me, please Therefore it deserves some true and complete care. So : do it.... Back in the late 90s I was given a heavily used and beaten up crest audio 8001... Half of its power Ts had been somewhere else.... But first test on a variac was still promising. So I accepted the challenge, and months of cleaning full dis/reassembling/rebuilding later it performed like new. And since then I have a pretty powerful workhorse which can do 1.8kW bridged into a two ohm load continuous, if needed. Cheers.

Wow, I love Yamaha audio gear but this is a new one on me! Please continue with the restoration, this is so unique.

Obviously restore this rare piece of Audio History.

i remember these from my days at the Yamaha repair center in the 80s - 90s , good luck ! ;-)

Cool intro and yes, full restoration please...good luck!

It's a cool amplifier to have in repaired/working state, but I'm not sure I'd rebuild it completely if it was mine. I have an Adcom gfa-1 sitting on a shelf that could use a rebuild and I haven't bothered with it yet, lol.

It's always tricky to know what to do in these situations, will it ever be reliable, is it practical to restore it back to original, is it better to rebuild it with modern components to make it better than it was originally, how much work are you willing to put into it and would anyone appreciate everything you have done or will it just get people saying 'you've ruined it' ? Basically it is a curiosity at best unless it is fully rebuilt and even then could it be used as a daily driver ? It has more limitations than possibilities unless you redesign and rebuild it but in reality you are just putting a new amp in an old case.

can't wait for the spherical amp next

Must be a pain in the arse to work on as xraytonyb did a video on one and had issues repairing it.
