Philco model 18 (code 121) - HELP!

Pith it doesn't sound like your power transformer or the 80. Your power supply sounds fine. I'm making the assumption that your 80 voltage reading was DC from the filament to ground. Let us know if it was something other than that. Some where the power is not getting to the radio so there is no load. No load means the 80 will read high. Speaker plugged in? Test field coil for open. Check large wirewound resistors for open. Follow the schematic from the cathode (filament) of the 80 and see where you loose it.
