Many of our beloved old radios have been sitting, cold
and quiet for many decades.
Some of them getting close to a century.
Recently, I've been dealing with bakelite and phenolic
in our sets which have taken-up moisture over the
years. Right now on the bench I have a TCS
receiver in which one of the pins of Z202, an IF
transformer, is leaking B+ to ground through
the phenolic. Pulling an IF from a TCS is a pain
but do-able.
So may we discuss ways to gently drive moisture
from our sets? I can "get rough" in the stove with
those bakelite inserts in WWII radio connectors but
that won't do for a whole set. I've tried powering
just the filaments and leaving a set for a couple of
days but I don't think they get hot enough to do much
good. Heat lamps can do some damage.
What have you done? I'm thinking of light bulbs
with the radio in a thick cardboard box, *outside* in
case the box decides to catch fire or something.
