Hello again, evereybody. I want to close the loop and tell everyone
what I found out in regard to repairing the symmetrically shrunken

TOO HARD.
I opened the cases and found no burst or dried-out caps. What I -did-
find was a

(3:4) then this may be in the power section
I've heard of this capacitor plague before. Hmm, replacing some caps
does not sound too difficult.

Hello, all -
In a previous (business) life I did a lot of support / hacking around

you could try the classiccmp.org mailing lists for
help. Or even the Electronics_101 yahoo group.
Probably other forums on the net besides.

Capacitors in the tube driver circuitry will do that
as they
age. Not so well sealed electrolytics will either
