I've started looking into the very weak and garbled reception in the set (I have the HS-62A version of the chassis seen in the schematic). Powering up on batteries for this set did not change the poor reception so I injected an RF modulated signal onto the grid (pin 6) of the 1R5 and checked to see what I got out at the plate (pin 2). I have a vintage Lafayette KT-208 signal generator and tracer. The tracer probe picked up the modulated tone applied to the grid but nothing at the plate (well there was a motorboating sound but it was not the modulation frequency). I took the 1R5 out and replaced it with another but got the same result. Both tubes check ok on my Jackson 648R tester.

My voltage around the 1R5 are:
Pin 6 67volts
Pin 3 37 volts
Pin 4 -3 volts
Pin 7 1.2 volts

R2 measures right at 103k ohms and pin 3 of IR5 to pin 2 of T-1 is dead on 22k ohms.
I've cleaned the tube pins and socket and do not see any misconnections. I'm thinking I must have a problem in the L-2 oscillator coil or T-1 IF transformer, neither of which is good news I think. Time to think about things...
