Hi All,

I have a very nice Model 80 where I replaced all caps and rewound the oscillator coil (was open). I made the changes listed on the Phorum re: the 2 meg resistor and the other changes recommended. The radio only plays one channel (570am), a strong NY station. It is very clear and loud enough, even w/o the antenna hooked up. It does not play across the dial. I have to be tuned in to get it.

I switched the oscillator connections in case it was wrong and have the same symptom. I would it very carefully with about 18 turns of number 40 wire. I am not sure what to do, as I have checked everythng several times with no change or problem noted. I adjusted the regen and other trimmers with no change as well. Not sure what to do. Could I have amde a mistake on the coil (its the second I have done, the first was a Model 60 and plays great)?

Any help is appreciated.

Thanks,

Steve
