Good morning, all

I am still working on the chassis of my 48-1262. I feel that I am getting close, but I have two issues that need resolving: a hum with no reception and the oscillator test shows + voltage instead of -.

Trouble shooting guide points to bad C103A and B if abnormal hum is present, but these are new and were checked for correct capacitance. R102 was also a suspect, but it tests just fine.

Voltages are good except test point D is a little low. Voltages are correct on the 14AF7 as well. The oscillator coil test at 3.0 ohms instead of 3.8.

Any thoughts as to where I should check next? I only test equipment is a Fluke Multimeter.

Terry
