There was one more thing I forgot in my previous post. In the troubleshooting tests in the info Chuck sent me there is an oscillator test. In it, they say to connect a voltmeter between pins 1 and 4 of the 7F8 (refer to the schematic posted above) with the positive lead on pin 4. It says you should read about -3v. When I do that I get +4v. When I measure from pin 4 to the chassis, I get 0v. When I measure from pin 1 to the chassis, I get -4v.
What do my results mean? The attached instructions are for the FM tests, but the AM oscillator test is identical.
Thanks,
Rich
