In need of some help on a GE model GD630. Replaced the filter caps and all the paper caps, did not change the brown mica caps and only 4 resistors. All the tubes have been checked and are good. It has a Ballast tube BL-49B, the voltage drop across pins 8&3 is 46.4v and pins 7&8 is 4.7v it is about 2v lower than it should be but steady.
Now the part that has got me going in circles. I turn it on and I get a hum (after it warms up) not real loud but its there as I turn up the vol and get nothing until about 75% rotation on the pot (10k checks out ok) I get sound (stations) but the vol is loud and distorted. All the heater voltages look good (maybe low about 1v) . Could I have the polarity of the filter caps reversed? Bad resistors? When I got the radio the filter caps were missing. Tried to go by the voltage chart but nothing matches up. Any idea's
