Hello all,
Just managed to get hold of a Sony TA-4FA, this was my first amp many many years ago and just got hold of one on eBay. Very excited!
Have a few bits to clean up on it and a wobbly volume pot to fix, but the main problem is faults on both channels.
I've received it and it has very badly distorted audio on one channel, no audio on the other channel.
I'm going to guess I'll be needing at least IC201 (CX171) and possibly Q201 & Q202.
Anything else I should be looking at for this fault (other than, of course, going over the whole board?
I've been able to source 2SA771 & 2SC1986 but can't find the CX171 anywhere anymore, anyone know someone that might have a stash of them laying around?!
Thanks in advance for any tips.
