In the first post he noted the transformer and rectifier have been replaced. So it may not be rubber coated. But your right, my 39-30 transformer is all rubber (in addition to the rest of the chassis). As was the two 39-6 chassis I have. Odd though that it doesn't have rubber wiring in the chassis. I think every '39-'41 Philco I've ever touched was at least half rubber wiring.

Still not a reason to do a proper electrical restoration of caps and resistors though. And cloth wiring isn't 100% safe. It still cracks and exposes wiring over time. Granted not the the level the rubber stuff does. But it can still be a hazard if not inspected.
