Replaced all wax capacitors,with sprague orange drops replaced all electrolytic caps, all the voltages are dead on.The problem is the tone control.It is muddy and too much bass from the left to almost the whole turn of the pot.there is no treble til right before the end of the pot ..Dirty pot? bad pot? or cap Change?

Yeah. I would say the tone control is very dirty or has an internal problem. May as well take it apart, clean it up good. Test the disk and the wiper contacts on both the center contact, and where it rides the disk.

I just noticed the speaker paper is split.replacement speaker or recone?

Hi Robert,
Yeah, the speaker may need re-coning or replacement. Often times you can repair the "split". I've done it using nothing more than tissue paper and shellac. But, this won't answer your problem with the tone. Tone control may need to be taken apart, cleaned/adjusted or worse case-replaced. Make sure the resistance readings are accurate across control from wiper. Good Luck.

Hey Joe , Thanks for the tip. If I have to replace the pot .is it a 100k 1/2 watt audio pot? thanks rob.

The pot is a LINEAR, not audio. Otherwise, sounds good.

Hey Rob,
Actually you can find the schematic for this set right at this site under Resources. I just looked at it and it's calling for a 50K control. (R25) Schematic isn't that great, but it'll do if you scrunch your eyes!

HI, yes .Ifound some resistors need to be replaced, carbon comps are reconizable. What do I replace the hollow tube resistors with ? Thanks...Rob

Rob: I know the ones you are referring to. Unless someone knows more about them, I don't see any reason why you can't replace them with a regular carbon resistor of the same wattage. Mark from Kalamazoo

And, of course, the same ohms! The are all 1/2 watt except R36,R37,and R38 according to my schematic.

Thank you for all of your help. I'll write back when the radio is finished. Thanks again ...rob

Robert: Your 7G01 is similar to my 8Y02 and many other Zenith AM-FM models of the 50's. Mine had a problem with too much bass - like being next to a car full of teenagers with rap music playing. Check all of your resistors in the audio section carefully. I found some that had drifted up in value and another that was open. In fact, I think that if you search the postings on this site you could find the suggestions I received. Mark from Kalamazoo
