Bruce, The tuner control module is likely the
problem on this oldie.
PTS sent a notice out many years ago stating thus.
There is a cap on the solder side (tack soldered in
a sleave) that you simply cut out and throw away.
Also resolder ALL the stakes around the edges of
the board(MTTxxx).
I'm not in my old shop right now and cannot be more
specific.
Hopefully, someone else will take this up.
If not, I will try to find those old buletins
tonight.
