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.
