The transformer leads are deteriorated, but seem sufficiently intact and are easily reinforced with the shrink tubing, which has a heat setting adhesive that may make the old leads sufficiently robust. This would not however be safe enough for use on campus. 

I fpund the 2 leads that have highest resistance for the 110/120V AC input, ~3.4 Ohms vs. 4.1 Ohms. I'm using the 4.1 Ohm pair for input. I also tested the high voltage output at 699 VAC, and the #80 tube filament voltage at 6VAC. I need to try the centertap lead, and I have yet to test the remaining leads, but they are now as safely covered as I can make them.

The insulation on the old leads had broken down where the wire was bent around parts of the chassis and/or near connections. I suspect it was potentially deadly left as it was. It had crumbled and fallen iff in several places.  

Applying heat near the "tar-like" substance in th     e transformer is interesting, it seems to vaporize at a fairly low temperature, I suspect its flash point isn't much above the heat gun temperature. All very interesting!

I'll remove the inductor unit next and check it out. Perhaps the shrink tubing can also save it.

Any suggestions will be greatly appreciated, thank you.
