The schematic says control grid which is G4. PIN number 4 on the tube. Should be .18 volts. I have removed the coil and tried winding it backwards and forwards. No difference whatsoever. These radios from the 1930s are an absolute nightmare to work on. AA5 radios form the 40s and 50s can have all weak tubes, rotten wire, and shorted capacitors and they will still work lol this radio is going back in the attic where it belongs. I appreciate everyone’s help, but this radio is not going to work again. I might just sell it as a parts radio, even though it is in excellent condition…
