Just went through every step on the "Correcting Intermittant Operation" page, with the exception of #8, which is "Oscillator Coil Impregnation".

Could that be the culprit? EVERY time I increase the tuning cap (to 1200 Khz, exactly), it quits oscillating, and I follow the same procedure of switching wave band switch to police, tuning cap to max unmeshed (which brings back oscillations), tuning cap BELOW 1200 Khz, and wave band back to BC, and it works.

Rotor shaft on tuning cap grounded throughout entire movement, wave band switch good, etc. etc.

Bottom line: quits oscillating at 1200 Khz.

I even changed my shirt, and had a different breakfast. Didn't help.
