Very nice video, thank you. I really wonder the artistan printer results with high end materials like PPA CF, surface quality etc. And also, do you have machined part samples for pa cf or onyx?

I have this same amp, just in black. Running 7.2.4, with main 5 channels running thru the amp, & 4 atmos going thru the main AVR. Both units run surprisingly cool in my setup, which is what I was more concerned with, rather than trying to improve the sound.

Hello, I bought one 4 years ago. It works without restoration 🤞 But I want to change the speaker connections as you did. What part number did you use? Or what dimensions do I need? Thanks!

Spot on! The preamp adds flavour, so that is one more variable and one more option that you have (using a different preamp, and I would use a DIY one!)

Thank you very much for your restorations videos! I have the same amplifier, trying to restore it as well. How had you took off volume control handle on the front panel?

The MOST UNDERRATED channel about restoration and repairs!! Period!! Tidy desk, good lighting, proper analysis of the issue, careful repair planning, attention to detail, absolute pleasure to watch.

Killer job mate

this is brilliant. great channel and video

Can you link to the original Transformer Box you mentioned in the video?

Awesome! I've had my 111 since new and this is where I'm at. I figured it was a belt, but have done nothing about it...yet. Now I know, and feel reasonably confident I can get it working again. Have always loved it and really didn't want to lose it. Thanks!!

Those speaker connections are brilliant. I could use a set on my 5650 unit. Any chance on selling them? I dont have a 3D printer. I made an insert for my main caps also, but not as fancy as yours! Keep up the good work. Impressive. Jan (Netherlands)

I hope someone has the right amount of money to buy this amazing amp from you, compensating the amount of work you have put in it to restore, in this quality!! Your videos are improving as well :)

Great video! I'm still using the TA-N9000ES I bought in 1999. I just replaced the TA-E9000ES today with a new Sony ES AVR. You mentioned that the amp won't support 8ohm in BTL mode but I checked the owners manual and it says BTL is supported from 8-16ohm. One the back of the amp it says "BTL USE 8ohm MIN". Am I missing something?

How do you get the front cover off this unit?

Curious, what laser speed/power settings are you using for the silpad material? And what on earth needs a round silpad? Great video and voice over work! This takes A TON of time to video and edit so I appreciate that you take the time to do it.

I 50/50 on changing out the trim pots. I test them and if they are able to achieve their full range without any "dodgy" spots in between, I tend to leave them alone. Maybe I should consider replacing them regardless. Which trim pots do you normally keep in stock? There are so many variations on trim pots that it seems like you could spend a fortune just keeping some in stock.

Not sure why you bend leads over though. Do you dislike your fellow technicians (LOL)? Bent-over leads makes desoldering with a proper desoldering gun considerably more difficult. It is not any more difficult to solder the leads straight than bent over.

The thing that always perplexes me about these restores is that the amount of labor would seem in many cases to far exceed the monetary value of the unit itself. Like in this case where you're going over all the solder points for hours. I can understand in the case of a personal project, but from a business point of view the amount of time invested would seem not to make sense to a customers point of view. Lol, that's a question.

No need to excuse yourself in any way, because to my best knowledge you're actually the only one who've made an in-depth full documented repair of this legendary (for good/worse) power amplifier. It's a privilege and an honor watching your struggle and satisfaction along the way and I would go so far as to say you're doing pioneering research and groundbreaking scientific work and I'm not saying too much here or superficially back-padding. It is a pleasure to follow, like I'm sure it's everybody else's experience. I'm watching because I remember it like yesterday, when it was launched and reviewed in a local Danish HiFi-magazine 40+ years ago. The design alone had me at Hello, back when I was a freshly made teenager and yes. I've been drooling ever since. It's your kind of restoration, that comforts me in knowing that an amplifier like that would be restored faithfully and then put back into service for a multiple of decades. In fact, if my financial situation allowed it, I'd buy it from you for your asking price. Other DIY-repair RUclipsrs are doing tremendous work as well, no doubt about it. But none have digged into the Yamaha B6 so thoroughly and that's why I salute you. Cheers.

How is the custom Lundahl transformer project coming?

Ahhh, soldering pron.

That's some epic work man!!! Never seen this amp but it well deserves the TLC!!! Wondering if I could design, 3D print and build a scaled down version, say with a small class D amp inside for my desktop speakers. An excellent CAD exercise. I took the oval speakers from a TV, designed and printed the enclosures. A mini B-6 will be fine addition to the desk. Looking forward to Part 4 of your B-6 journey!!!

So cool! Can you provide a list of all the equipment you used?

Well, from that manual, this is something like Yamaha marketing department trying to defy the laws of Physics. What a pile of bollox!!!

Cheers for this, just bought one, fits perfectly underneath wall mounted component drawers depth wise, and even on the relatively quiet medium speed, it pulls solder and flux smoke in from an impressive distance with zero smell emitted from the carbon filter.

I saw your video on this magnifier, and today I bought one. Basically as new for only $200 USD. Thanks for the tip!

Thank you for the vidéo ! I am trying to repare my 330B (being a novice). When in Stereo, the left channel is very very low, no matter how the balance is set. If I switch to Mono, the sound is ok on both channels. It is doing the same wether I am on Spkr 1 or spkr 2. Do you think it could be the same problem as in your video ? Thanks !

Having been to a few restoration channels, this ones got the best SNR. Calm, clear and relevant commentary. And that mini switch surgery was beautiful!

Literally the Carver design verbatim.

I’ve been using this same scanner for 12 years. It’s been pretty great. Of course, now I’ve jinxed it 😂

mate... silMIC, not mac... bourns... not burns...

Hi, I have a pair of Yamaha AST-T100 speakers, please can you tell me which cartridge I should use? Thank You

Just the video I was looking for, thanks! I went through the cleaning process you outline the best I could, and am still getting a line that goes across the whole scan. It's the same color as part of the image I am scanning. Any idea what that could be? Perhaps I missed a spot? I hope it is something fixeable... Love this scanner.

Just restored a AU717. Its so much work. Much respect. Beautiful work you did.

Excited to see what’s next! I’m willing to throw in some coin to a desoldering gun fund for you ;)

Awesome work, really enjoyed your videos. I have just gotten a B-6 and will be starting soon. Would love to know how you were running the PS separate from the amp.

This is the reason why you should not buy old gear Problems on top of more problems

Definetly the final boss.

Crazy stuff. Respect!

as AVE would say:¨focus, you fack!¨

Awesome content

Very nice, so satisfying seeing it come together. Great work!

That triac removal...I would have had 3 soldering irons going LOL

Awesome work man - getting there!

At this point you can rename the amplifier from Yamaha to Theseus :D Amazing work!!!

As with most good channels the video work takes as long or even longer than the item being worked on ! Very few people understand what goes in to making good videos because they don't even notice the cuts and camera angles and lighting when it is well done, there are even phone apps that do a lot of the editing for you so most people are content with pretty simplified low effort content but it is far better when the video is planned and edited manually. No need to apologise for taking a bit longer to get around to completing the rebuild, it is worth waiting for and makes a great series !

Incredible work as usual

Keep up the amazing work! Thank you for the great content.

I salvaged,...I think 5 pairs of the sony 250 outputs when I tore down a 777es.

I have a untouched 4650 that works brilliantly. With matching speakers and record player. Threw away the reel to reel though😅
