I'm restoring a Philco 48-482 and have it sounding pretty good after replacing a gazillion caps and resistors and going through the complicated FM alignment. A remaining problem is the separate Bass and Treble controls. They are both totally dead with no noticable effect at all. At first I was puzzled by the fact that the ground terminals didn't seem to ever been used but I have since found a post here on the Phorum that the pots are sometimes grounded within. Still, I went ahead and wired them to the schematic. Still dead. I checked the resistance and the ohm meter gives perfect readings, the treble is 500k and the Bass is 1 M, and the tap seems to operate well, one is linear and the other has a taper. Logic is telling me that with the correct resistance the pot should be working. What am I missing? As a lot of you guys know, this radio is a lot of work. I hate to give up and go without the tone controls. Thank you for any knowledge that you can share.
