Hi Dave, yes I will do the cap swap next. I know the electro's are ok
because I checked not only value and ESR, but also Q. From
correspondence with the OP he found the 100nF cap (Ct) at pin 4 of the
3842 was "leaky". The problem may be due to the fact that most of the
caps around the IC are 50V monolithic ceramics, including Ct, and
while the voltage rating would seem to be adequate, I would feel
better if they were 100V MKT film. So that is what I plan to do.
