I have an old Morse brand FM stereo / phonograph unit (model 74452 forthe extra-curious). The volume crackles horribly when I turn it up anddown. I have the pot half-disassembled and half-disconnected.I am thinking that I can either clean it, or replace it. This is a 30+year old stereo, so I would like to replace it, but it is a double-pot.I've googled and such a bit, but I've not been encouraged with theresults. So, I'm back to cleaning it. I have gone through some pastposts, and it seems that while cleaning is an option, it is notguaranteed to work for any significant period of time, if at all. I maytry to get some cleaner tomorrow, but I'd like to know what you maythink of the situation.Details on the pot - It is labelled with the following:Top Pot - VR-23J M 250Kohm AX2 SF J62X (or J82X, not sure)Bottom Pot - 3A125VAC 1.5A250VACSo, as you can see, the pot is double because the top is for volume andthe bottom is for power. It clicks when you turn it all the way CCW.Also, one of the wires from the wall plug goes straight to one of theterminals.Basically, my question boils down to: Is there any hope of replacement,or am I stuck with seeing if I can clean it?I can post links to pictures if anyone wants a look.Cheers.

EH, just how are you "cleaning" it? Trying some "tuner cleaner" shot into both parts - would have been a good start. Good luck on getting it back together and "working".L.

Echinos spake thus:

You may be SOL; those other 2 terminals on each pot might be (probably are) taps, and the likelihood of finding a matching part, I would think, is pretty much zip. Were there wires connected to those 2 terminals? If not, you can use an ordinary pot.
