Hallicrafters S-20R

[bob91343]

I measure zero resistance from the middle tuning capacitor section to ground. There is a 33 Ohm resistor in the 6K8 grid and if I put an antenna on that grid cap the radio works. It appears that the 6SK7 rf amplifier is amplifying but its output isn't reaching the 6K8 grid.

If you have parts, I need a few things, like a Bandspread knob and the diagram of the external S meter. The speaker cone is torn (so far, patched with cement). I have repaired two of the rf coils that were burned out but I admit to not bringing them back to factory; one required 38AWG and I substituted 36. The other, a little bigger, still used 36AWG.
