WTB: (2) 100K Log Allen Bradley Pots for LA2A Project

[jazzcrisis]

I'm looking for two Allen Bradley 100k pots, log taper. There are plenty of linear types around, but log seems hard to find. I know there are alternatives available new, but I'm trying to build an LA2A with all-original parts and these are the last two pieces I need.

Maybe David at Studio Electronics has some?

I have seen that site and have heard from a few folks that when they ordered those, they ended up something totally different and un-suitable.

If you haven't used vintage pots, you may want to just go with the new ones. They  will at least give you a few years before they go noisy. I find old ABs all the time but when I build LA2As for customers I use new PECs instead. They sound the same, minus the noise.

A lot of people go out of their way to make everything original, not realizing they could make a better build by picking and choosing where they are using vintage and where they're using modern parts.

All the friends I know that built LA2A with PEC, had problems with scratchy noise from the POTS.
The PEC pots were new, I've read in some threads other members having the same problem with PEC pots even though they are really expensive.

Problem was solved by replacing the PEC pots with inexpensive ALPHA pots

I've used dozens of PEC pots and never once had noise from a new one. Though, they can commonly go noisy after a while, just like the ABs. Some go in a couple years, some never seem to go noisy. If you want that specific tone, that's one of the consequences. If you want ultimate reliability, there's much better options.

What Tone?
