I have a Philco 42-340 that I have recapped and replaced 2 tubes, everything else looks good.
when powered up all I get is white noise up and down the dial so I stated checking IF coils and all looked good until I got to #32. The one side White and Red I read 32 ohms but what would be the other side Green and Blue I show open. Now this has one of those compact units PC51 (#32 B, C, D) that has a resistor and two caps. I suspect the resistor is open and nothing in the papers I can find gives me a value. I do read 400pf each for the two caps. I have no idea what the resistor would be? I'm using the Schematics from 340 and 345 as the latter is much better quality and they seem to be the same in this.
