Philco 46-480 Electronic Restoration
#7

I'm still combing through the chassis, but I just found something which doesn't match the prints. R305 connects to pins 5 and 7 of the second IF 7H7 tube. Every mention of this resistor in the manual indicates that it is a 150 Ω resistor. Even the listed part number would hint that it's a 150 Ω resistor. However, I see a resistor marked brown-grey-black-silver (15 Ω with a tolerance of +/-10%).

Does anyone have a 46-480 who can double check this resistor?
