Gene, going to pull them up on YouTube and give a listen. Upstairs at the bench dissecting PL 2000 preamp volume/power switch pot and balance pots. Going to try this in post #9.

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.
Listening to The Walkabouts.

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)
