I would stop operating this set immediately until the wiring has been replaced, the chassis is full of rubber covered wire that is usually deteriorating by now, and that includes the wiring going into the power transformer. I think the "rubber" they used may have been some form of gutta-percha or gutta-balata rather then rubber from a rubber tree, they used to be very popular for insulating wire because it wasn't attacked by mold.
