I disconnected all the inputs to the amp I/C. Still had the pop. You might want
to check the reply to Jim Meyers post. Paul

> I have posted the problem and haven't come up with a fix. It is an RCA
ctc197A. There are apparently variations in this circuit because the
collector of the mute transistor Q11900 has a .84 ohm resistor to ground and
0 volts. If I lift that resistor I lose the sound. Other circuits show 31v
on the collector. The problem is a delayed loud pop in the sound when
plugged in and also when turned off. I have replaced the mute transistor and
a couple of caps in the supply for the sound. Several have tried to help and
I am not unappreciative, but maybe no one else has had this problem.
