I found a schematic for a 46-1203. The circuit seems to be identical to the 46-1201 except for the addition of a 7C7 RF amplifier tube. The power resistor (R2) is a 50 ohm/120 ohm. Both units use a 50X6 rectifier. My 46-1201 power resistor has (measured) values of 41 ohms/68 ohms. Can anyone explain the purpose of these resistors? What effect would raising or lowering the values have? By the way, after the recap and alignment check, the radio works ok for an AA5. However, before i move on the something else (i.e. the turntable) I want to make sure the power resistors are right.
