what are you listening to?

I never had the guts to dissemble these. Always sprayed DeoxIT and injected fader grease. Filthy inside. Green copper sulphate on the fader contacts.
Could probably clean with alcohol/Qtips, regrease, and be good again. But going to look at the links SupraMan posted.
The balance pot uses ring terminals, the volume/power pot uses bayonet. Might be a problem.
Balance pot above, volume pot below

Going to clean and reassemble those old PL pots. After a lot of thought, think I'll use a single new Bourne's 100k pot in place of the original dual 50k balance pot, and go with one of those stepped two channel attenuators with the precision resistor array for the volume control. Been putting it off for a long time, but it's the way to go. May or may not keep the power switch. May even use one of the resistor array attenuators for balance. Need to see what's available.

I was a little confused when you went back to the dual pots, George. I also yanked the dual pots and went to the single gang design based on the work you documented several months ago.
 
In my experience the stepped attenuators are far quieter than any pot out there.

I also think it’s a good place to use quality film SMD resistors.

The downside is the size of them… otherwise no downside. (Coat really isn’t because you need to pony up for a pot anywhere near the sonic quality of an attenuator)

i would try to do something like that....i started to work on it when i had a replacement in hand...
lol....
projects like this normally dont turn out well for me...
lol
