Philco 37-611

I removed the damaged wiring traced it out and re-connected the speaker.

I actually have audio - meaning the amp is working. I'm sure it will be a lot better with new caps but I can put a signal in at the volume control and I hear it from the speaker.

What i don't have is any radio, nothing no static nothing.

The schematic, the factory Philco one has on the first page for 37-611 a block diagram with voltages on the filter and the tubes.
They show a 2.4vdc voltage on the det/osc and the IF amp.
It looks like it saying on the cathode... does this make sense.
I'm measuring the voltages they call out using the neg of the main filter.
All the other voltages they printed, are very close, however there is no 2.4vdc on those tubes.
