Not sure where this should GO.. So if in wrong place please move...


Ballast resistor. Hytron K42B.. I am sure this has been asked already But cannot find a schematic or Pinout of that tube.. With Resistance Values..

This is in a GE H632U Radio that I am starting to work on.. schematic for radio shows 2 resistors in series with the pilot lamp across one of them..

I tried to measure the tube and from pin 3 to 7 I get approx 3.0 Meg and from Pin 7 to 8 I get approx 770K.. No readings on any other pins..

Is this correct??

Skip..
