[Milsurplus] Drying Out an Open Frame, Large Power Transformer.

[David Stinson]

This has probably been discussed before,
 but I can't find the threads.
I have a large open-frame power transformer removed
 from a transmitter stored in a damp basement for years.
People who store radios in damp basements 
should be moderatly tortured.... slowly....

I'd like to dry it out and test it before reinstalling it.
I've heard of a box with a heat lamp, putting 4 or 5 volts
on the primary and shorting all the secondaries to gently 
heat it up from inside, etc.
What are the recommendations for this?
