By the way, in the parts list, the 10uuf cap is designated for use on the PT7. So at this point I have negative voltages, <1V and reading negative at the plate, G2 and G3,5 on the 7A8 and high voltage,> 100V on the plate of the 50L6 output tube. Ant and osc coils show continuity and resistance as well as first IF but signal does not pass from 7A8 to 7B7 or forward from 7B7.
How best to test the primary of the 2nd IF without disassembly? Signal forward from 7C6, 50L6, on/off forward test good.
