Just another update.  Because of several tubes that were DOA, I started to check the power transformer windings for the correct ohm readings.  When I checked the HV secondary, my VTVM showed the hallmark reading of a leaky capacitor charging.  This should not happen as the HV secondary is isolated from the filter circuit.  I did some poking around the rectifier socket and found a burn mark.  When I poked at the burn, my probe went right through the phenolic right between the plate connections for the 80 rectifier.  I suspect the burn allowed a path to the filament connection, which would allow a connection to the filter circuit.  Anyhow, since the socket has to be replaced, it seems better to repl
