Any good idea to replace 20kohm volume pots on Altec 9440A

wow, rough crowd here sometimes.
@OP: Old amps can benefit from some refurb work, and while you want to be choosy about how far you want to go in replacing components, you can get a big lift in sonic quality or operational dependability if you fix up the right stuff. Here is a link that might help you:

I've not used the 9440, but I've read about it on some of the diy amp sites I visit... it is well-respected by many. Just do some searching around and you can find some help from people who have refurb'd these and put them to work in home hi-fi applications. And let us know how it works out for you. I'd like to hear one sometime.

I own and use a 9440 for live stuff, they are dynamite amps, way better IMO than the all worshiped DC300. However, they can be tricky to find today, as many installed altec system used the 159x family of amps and live rigs used the DC300 more than anything else. Even those amps that were toured with would be beat to hell and scrapped at the end of the tour. And on top of that, most people that own them aren't willing to part, funnily enough! I got mine for 150 from an auction guy that bought a load of surplus electronic equipment from the government, and really had no idea what he was looking at. He thought it was some kind of industrial power supply.

He thought it was some kind of industrial power supply.

Cosmetically, they are not unlike several power supplies made by HP in their 6200 series.

These amps can be found on ebay without having to wait too long, but they do sell high...... even the non-functional ones. I've never liked the look. I guess becasue whatever plating Altec used seems to corrode, and the faceplates are always scratched.
