Synchro-bias
New ClassA
I have matching ST-S7 tuners in black and silver for my 2 V8 amps. The displays were dim on purchase and i assumed it was due to failing and aging display.
I decided to take a look and in both tuners exactly the same capacitors had green on their legs, so maybe the caps in question affected the display
I was thinking of FM caps, to replace just the faulty ones? and with luck there wont have to be any alignment ? i thought silmicII maybe not suit for PSU, or maybe recap the PSU only , fix the other problem caps?
AN6552 looks like an opamp for output? OPA2604 in place? 2.2uf to silmicII output caps
green dots failed caps
