41-250 extra resistor or schematic eerror? -
FStephenMasek - 10-19-2008
My Philco 41-250 either has a factory wiring error, or the schematic in the Philco manual I obtained is incorrect. The schemettic shows B-minus going to two 470K resistors (part numbers 53 and 54), and the other end of each resistor to a grid on one of the 41 output tubes. My radio had an additional 470K resistor between B-minus and those two resistors.
Do you have any ideas, or have you worked on one of these?
