Well that was an exercise in frustration. Replaced the off spec 47k resistor, checked all the coils, got it all back in the can, checked all the coils again, soldered it all back in place and realized I did not replace the fish paper that was around the coils inside the can That can is not coming out again unless it really needs to.
Anyway, after all that, still no tone coming through. I rechecked that I could still get tone by by-passing the transformers with a 100pF cap and do hear tone faintly. I also still heard tone when I disconnected the by-pass lead with the 100pF cap from the diode plate (pin 4 of 1LD5) but still had the lead connected to the IF 1LN5 pin 2 plate. Is that telling me something?
