You can be absolutely sure that Philco did not install a 20 watt resistor in this radio originally. Have you done a current measurement through this resistor to see what the total set current is? If not you should as something does not seem right to me.
Greg,, how did i miss this post?
i couldnt agree with you more.. something is odd, yet my transformer voltages are all good.
radio plays on AM , no shortwave yet.
there is some risk but im willing to power up and spend the min time i need to gather section by section the voltage readings you all need.
While i had one meter reading each side of this resistor, i had my amp clamp set on "MAX" to gather and hold the max current draw and the display never caught a number. i can redo but that tells me the current is likely under or at an amp.
any other time i amp clamp using min/max scale it works like on mult-2000AH -48v battery strings, automatic transfer switches, Gensets, hvac etc.
dono man,, maybe i will open the circuit and put my meter inline with the input side of this resistor.
