Hello all,
I'm working on an old (white grill cloth) KLH Model 21 FM table radio, and the tuning shaft has pulled out of the variable capacitor. The info on the back of the capacitor is:
6620 151 25-771
TRW273
I'm guessing that 6620 is a date code, and either 25-771 or TRW273 is/are part numbers. I won't even guess about the 151. In the service info I've got the cap is C503&C509, KLH catalog #0025 and part #000771. I think the model 18 tuner and the compact system (model 20?) with the FM tuner used the same tuning capacitor.
If you have a parts unit that you are willing to sell the capacitor with or with out the attached board, please let me know.
Many thanks, Tim Schwartz Bristol Electronics
