[Milsurplus] [BoatAnchors] Water, Water Everywhere.

I recall a similar discussion with capacitors a while back...?

Main thing is to NOT apply so much heat to prevent making steam.  Ideal
set-up is 150 deg F heater / controller (sense point on chassis) in sealed
box fed with dry N2 with fan agitating over several  days.  This is frim my
Mat'ls Science guys in aerospace.  If this fixes it, I clean out cracks and
tracks and seal with GE Glyptol.

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.
