Re: Trying to bring back a AA501

Well it looks like the AA501 is not as bad off as I though. I got a service manual still need to go over it in detail however it looks like the fault is isolated to “higher frequency”, anything ~1Khz it looks like I am getting numbers that are at least in the realm of sanity. Anything over that and I get 100%+ distortion. I am starting to suspect ½ and opamp has gone out.
