Model 80 jr resistors getting hot
#1

Hi all I’m new to the forum and new to radio restoration. I restored 2 other radios in the past, but this is my first Philco restoration. I have two resistors that seem to be getting hot to the touch. It’s resistor nine and resistor 11. Resistor nine is a 9K 1 Watt and resistor 11 is a 16K 5 Watt. I replaced both resistors and the 9K resistor was replaced with a 9.1K 2Watt carbon resistor. The 16 K resistor was replaced with a 16K 5 watt resistor. The radio is running well and the performance is good and I’m receiving all stations across the band. All my voltages and resistance that I’ve measured seem to be close to the schematic measurements But I went without a miscalculation. The radio was previously worked on in the past because there were some modifications when I opened it up. The components basically match the schematic except there were a few differences. I’ll post some pictures of The underside of the chassis both before and after the work I’ve done. The radio has been recapped and all the resistors replaced because they were out of tolerance. I also replaced some frayed wiring. All the other resistors are cool to the touch it’s only these two resistors that are having the issue. Thank you for your suggestions.
