[Boatanchors] Baking moisture from power transformers

[Jim Wilhite]

I have used the big reflector heat bulb like those found in restaurants to 
keep food warm.  They put out a lot of heat.

I've used a 60 or 75 watt bulb in a drop light, under the chassis or piece 
to be heated, blocked up appropriately, and with a makeshift cover of 
cardboard, towels, whatever.

I've done something similar to that and placed the item or the chassis in a 
corregated cardboard box along with a 60 watt bulb. Close the box top and 
stick in a thermometer (like a candy thermometer - I bought a surplus lab 
one) and connect the bulb to a variac or dimmer to fine tune the heating. I 
find that I need to check the temp every 15 minutes or so at first but can 
fine tune the energy input so that it can sit for hours without much temp 
change. If you don't have a variac or dimmer, leave the box top partly open 
and use a towel to cover the opening, adjusting the size of the opening to 
control temp.
