I removed the pot. It reads open, so I measured from wiper to one end with it full ccw. As I turn it cw it got up to +/- 40k. Moving the meter to the other end of the pot and it read +/- 170k for a total of +/-210k. The parts list dose not give a value for this pot, just a part # for the pot with off on switch. Do you think 210k would be right for this volume? For some reason I was thinking it should be in the 10k range. I took it apart to see how the "fixed" limit works, and all that is is a positive stop to keep the wiper from going all the way to the end. From what I could tell the "fixed " limit is about 210 ohms to hold a 3 volt bias on the suppressor grid of the I.F. tube.
I think!!! Do they still make pots like this?
Thanks for the help.
Bob
