That will keep you busy for a while! The worst part of these are the power supply's, with everything encased in tar. I spent a Saturday afternoon smoking out the neighbors with a heat gun, melting 85 year old tar out of the power supply of one of my model 40's a few weeks back. Had to do it, though, as the power supply tested ok as is, but when I slowly starting bringing up the set on a variac, smoke started rolling out of the transformer section. Not a good sign! Then, naturally, as soon as you start heating up the tar to get it to soften or melt, it also melts the solder joints, so the wires fall off of the transformer, choke assembly, and cap section. Here's what's inside:
