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.

B-6 exploding? You don't wanna see that the b-2 can do :D

Go for it, probably won't get a chance to work on another so obscure.

BEHOLD THE OBELISK ⬛

An old and cheap receiver I don't know what the enthusiasm is here

I have one that is starting to have issues (loosing sound on one side, or static noises when it is on without anything playing) do you think it is worst it to send it to restoration?

At that time i believe the Luxman D109 was the top end player

Excellent video and discussion....very informative. Have a Luxman D-117.. was advised to stay away from the Chinese laser replacement as compared to the original discontinued Sony laser . However bought the copy version and after watching this video surely will leave the installation to a professional .:)

Hi, I have Harman / Kardon AVR 171S which is behaving very weirdly. It's a 7.2 channel network receiver. Off Late, I could notice that the Front Left channel has lower gain than the Front Right channel. If I automatically calibrate the speakers using the provided microphone, then this issue is getting rectified and sound is coming correctly from all the channels, however the volume level get greatly reduced due to which I need to turn up the volume in order to get good quality sound reproduction. However this is not convenient and if I reset the unit to factory setting, etc, then again the earlier issue is re-occurring. One more issue I would like to highlight is that there are about 6 HDMI outputs, and the MHL o/p HDMI is not generating any signal and hence I had to connect my Shield TV media device to another HDMI o/p to make it work. In my understanding, I don't think there is any issue with the amplifier MOSFET transistors. So it could be something to do with the o/p circuit, but I am not that technical to comment further. Can you provide any insights based on your experience and can guide me with your suggestions?

That model looks real good but, i wonder how at 575w total, with big heatsinks that deserved new thermal paste before blowing everything i guess, i just pushes that wattage. Compared to Sanyo STK, i am sure with my preamp, i could push the same with HiRes quality the same wattage or more with the fan working, and it does have so small of a heatsink compared to that Sony. Good video, at least it works, i felt bad looking SMD under the hood...

I had one of these in my youth. Loved it, eventually replaced with ARC SP4 preamp and a variety of different amps. It had a very unique Class A amp type sound. Definitely better than the Marantz 1030 it replaced.

I decided to use one as well, how is it working for you?? I've replaced mine PCB with ESP32 and connected it to Home Assistant :D

thank you for this :-) bought for the same reason, id be interested in seeing any future mods you do with it :-)

Potentiometer everyone can be demolished and folded. 1.1 mm drill, make a hole, thread and twist with a screw. A lot of fun.

Is this power transformer a toroidal transformer for this Amplifier？

Hey! We love your work and want to get in touch!

This is outstanding work. Please keep the content coming!
