Hello sir, i understand it’s been 5years ago. Could you tell me ….i have 2 resistors on my PCB board for the lights. Did you replaced two of them or just one for 8.2k..? To install led bulbs. Thank you!
Thanks . Really good video. In 3 days going to pick up this amp (350 km in one way). As the owner sad, he has it for 40+ years, never had any problem. Nobody Touched it inside - what I like. I'm an industrial electrician for more then 25 years, and in this aria, my last project for fun was sansui au 7900, the owner was happy. Hope this video will be very helpful to restore a new toy. Right now I have KEF 104/2 and Tannoy srm 12x with only one amp - Marantz PM 8005. Hope this amp will work well with one of those speakers. (They are realy different :)
I acquired my very own smaller sister amp the Yamaha CA-510 amp brand new on my 15th birthday back in the fall of 1978. I also remember seeing and experiencing the more powerful CA-810 next to my soon to be purchased 510 in the sound room at the local stereo/record store A&B Sound in Victoria Canada a once iconic Canadian music store chain. I loved that amp, when it was in its prime in the late 70's to early 90's. Sadly the old CA-510 finally died in smelly, smoky fashion in the early 2000's. I would love the get the new Yamaha retro CA-inspired A-S1200.
Those THD #'s are what one can generally expect from that era Yamaha! They were always my favorite equipment! We wouldn't even consider dropping down to Pioneer! The meters were a nice bright even pale creamy white color...no blue whatsoever? And yes, we purchased these new in the mid-late 70's. We chose our equipment by reading the specs! THD & IMD also the frequency response as well as the S/N ratios. If the numbers weren't there, I didn't even want to hear it ! The only problems I can remember were replacing the wheat lamps every now and then, but well worth it for the performance...
Very nice! Whats your opinion on replacing filter caps? Historically, I always replace but trying to find anything in the 12000uf to 18000uf 40mm casing is about impossible. Digi, Mouser, all 0 stock. I'm to the point of salvaging early 2000's amps for filter caps.
Interesting about the pre main in-out, important because I just had this shipped to me via EBAY, and we know how these people package. That was my 1st thought silicone for those big caps, however did not know you need the (type II silicone), so Thanks. Waiting for my lights, surprised yours had a Green look and not Blue. Very odd acting VU Meters.
Great amp. 3-4 weeks ago I rescued a CA-810 from being scrapped. Yes, some people are insane and I was glad I was there at the right time and rescued it. It works as it should, but I should restore it and also replace the relay which takes a good while to activate. Need to replace the lamps too. Great video! Greetings from sweden.
With fan cooling base I used to drive 2x 200 watt theatre bins for the town discos and parties ('76) Later used last summer driving outdoor sound for village event- such good amplifiers...
How much did you charge for this restoration and what is your turn around time if I send you the exact same amp. If I had to guess off watching your video my speaker channels are bad. Great video I have none of your equipment or any skill set in this area of electronics. I've already been ripped off for $180 from a local shop that did nothing other then turn it on and gave it back. Also, brand name and dealers that sell that cleaning pen you used. Thanks
go too high in voltage can modify character of amplifier because the higehr voltage the higher ESR (capacitor resistance) The esr is a parameter taken in consideration in manufacture conception
Thanks for your great videos, a big fan of your channel. I have the same amplifier and want to line the phono switch up with the markings. Could you please tell me what type of locking screw tool and size to use please.
Problem exist between KEYBOARD and chair.

I love yamaha amplifier
Very nice amp and great job .. love the thorough explanations of the situation and cures. YOU are one of the very best here.!

I have CR 800 bought new when i was 16. Still sounds good but should i go into it?
I have a CR-610 Yamaha amp

Very detailed and systematic narration, I am very thankful as a beginner.
I have one of these amps. Do you still do restorations and what might the cost be?
Just proved my SU-V3 still works with the help of this video! First amp my dad bought me as a kid. So glad to know it still works!
