Hello Guys,
i will Recap in the next time my Yamaha A-720.
For now, only the Electrolytics.
I ordered some Capacitors at partsconnexion and still waiting for it. (Canada -> Germany) takes a while.
I ordered a few Nichicons KZ, 2x Nichicon KG (22.000uF / 80V), 2 Elna Silmic II, and already have Nichicons ES BiPolar.
:scratch2: Is it recommend to change in Step 2, the Polypropylen Film Caps in the P/S and on the Amp Board? And whats with the Mylar Caps, should i change these ones? :scratch2:
Should i glue the new Caps on the Board? (against Mikrophonie Effect) or hat it be done only for easyer manufacturing apects?
I have to say, the A-720 is in an very great Condition, i think it`s never been running in CLASS-A Operation (There are no spurs of any Hot Times in it).
I had luck to become a non-smokers unit
Iam electrician with good soldering skills. But i´am new in the HiFi Business... so i have these questions ;D
i work especially in the High Frequency Range up to 67GHz. (EMI Measurement Receivers & Spectum Analyzers)
When the times comes up with the Project Recapping, i will take some Pictures and will open a Thread.
This is my STEREO Stack, Yamaha A-720, T-1020,K-1000
