Hey jcassity - I have about 260v on the plates of the 6V6 tubes. The Philco documentation says it should be 235. I'm measuring with a digital multimeter so I would expect my readings to be higher than the specs say.
The resistor I'm concerned about is the 15k 2W resistor in the power supply. It's R100 on the Philco schematic, R127 on Sams.
It's connected between the 2 can capacitors. It will be a few hours before I can take a new reading because I'm in the process of re-replacing some wires. 2 years ago I replaced some of the high voltage wires with some wire I picked up at the auto parts store. I decided it would be a good idea to go back and re-replace those with 600v wires. But when I measured it before it had 166v across it in FM mode, which means it's dissipating 1.84W. Even in AM it measured about 116v, dissipating almost 0.9W. I'll try to get a new measurement later today.
Thanks!
