[TenTec] PTO temp compensating cap?

[Clark Savage Turner]

I have tried a few things to clean up the drift in my Corsair PTO 
(physical rebuild, resolder all connections, re-work the physical 
connections and hardware, replace varactor diodes, check crystal 
oscillator to eliminate it as the cause...)  The poor thing goes over 1 
KHz in the first hour and keeps going after that.

Now I think maybe there is a bad cap in there.  I am going to take out 
the board from the PTO tomorrow, does anyone know which cap is the one 
used for temp compensation?  I have a box of compensating caps (borrowed 
from a friend) and can experiment with a couple till I get things right.

Also, if anyone has a spare PTO (I know I sold my spare to someone out 
there, want to give it back ?  hi ) - I would consider just replacing 
this one for now.
