Default So, im going to replace the Alps with a PEC...someone help?

My tech is going to do it for me (on my Jolida 102B) . I just need to know what part number the PEC(well built, milspec) pot is...and where to get them of course.

thanks for any help.

You use a KKA series part of the value shown in Jolida's schematic. You buy the pot. from DigiKey.

Just make sure you save the Alps to put back in when you discover that the PEC is unbalanced and noisy. Oh, and the PEC needs a different size mounting hole, so you are going to have to drill out the hole in the chassis.

ok, well, every ALPS blue ive had experience with has been trash, so can you tell me what pot to get that would work off the bat, that would be an upgrade from this ALPS?

It is between the GoldPoint, TKD, and PEC. I will *not* use any alps pot.

I have a goldpoint in one of my amplifiers. A real good quality part, I actually feel a bit guilty about spending that much money on it...have been thinking about selling it.

What about something like this. They're available in various resistances.

oh, it wasnt just this one, but 4 in all. the problem is that they get scratchy/noisy over time.

I have had the pot on the jolida replaced 2!! times, each time with ALPS blue(as per the factory).

I also have a custom built headphone amp that we originally used ALPS Blues on...again, noisy


i am quite frankly tired of dealing with it and want to buy something where I wont deal with this sort of thing.

I've probably used 30 to 40 Alps blue pots over the years, and I've never had one develop a noise problem. I have had some that were not well matched at low volume, but that's about it. Do you live in a particularly harsh environment?

Ditto on the PEC. I used them but was not happy with them.

A stepped attenuator or a TKD are my choice now. Have had god luck with Noble, too.
