Zenith MJ1035 volume control - replacements?
The volume control (2-megohm dual pot) in my Zenith MJ-1035 stereo FM radio is shot (the radio works, but I can just barely hear it). I'd like to get the radio working again as it used to. Are there any replacements available for this control? That failing, would I be able to use any standard potentiometer, or does it absolutely have to be 2 megohms? If the latter, I may have to junk the radio, as I don't think they make 2-meg dual pots anymore. I don't want to junk the set if I don't have to. When it was working, it sounded great, and I miss it.
Thanks in advance.

Eh, what's the part number on the pot? It should start with 63, typically 63-XXXX for a part number. I've got a good selection of older Zenith pots, all catalogued,
Cheers,

First, are you SURE it's the pot? An ohmmeter can tell you. A good pot will read 0-2 megohms from center to either end as it's rotated.
The Sams folder I have for the 1035 (NOT 1035-1) shows a dual 1 meg pot. I think either 1 MEG OR 2 MEG would be fine. AES has a couple of dual 1 meg audio taper pots with long shafts - tubesandmore.com. I would suggest getting one, THEN trying to fix the existing one. Start by googling "the secret life of pots". First step - spray with cleaner. Second, measure and see if the elements are good (2 megs). If so, disassemble and see if you can bend the wipers back into contact - even if the resistance element has a worn-out track, you may be able to bend the contact to hit a good area. or even sub in an element from a good pot... Anything can be fixed. Not everything is WORTH fixing, but should we let THAT stop us? |
