Got an old amp with frozen two frozen pots. Any advice, besides replacing them?

"Frozen pots" -- I thought it was going to be a blues tune. lol.
How about electrical contact cleaner?

Replace them, I know it's not what you asked but unless your amp has a restrictive PCB construction, it is an easy job, and you should have pots good for another 500,000 rotations.
You could try conact cleaner in the first instance, use a cleaner that is non-corrosive to the carbon tracks in the pots, some "switch" cleaners can do more harm than good.

My tech has tried to save frozen pots for me before. Took them apart, got them so they would move freely but there was always a "dead" spot in them. Like 5F6H said. Replace them.

So what pots would you recommend for a Masco MA-25P? Both are for input volume mic and phono. Thanks.
