2285B replacement trimer pots work :)

[Mike Sweeney]

Not pretty but they do work. I found out after I had ordered my first set of pots ( 1K and 2K) that the 1K pots had been changed on the schematic to 300 ohm and not the part lists 1K :/ And then I found I could not get the 300 ohm in the same model/series as my 2K. So now I have two different styles. They work but it's not as pretty as I would like. I saw someone who made a PWB for this and I might try to do that myself a bit later once I have all the major reworking done. And yes, single turn pots are twitchy but the only way to get multi turn was to put them on their side. Which I might do even though it is a bit tricker to do the adjustment. But I only need to do it once

They still sell these https://www.mouser.com/Passive-Comp...ers-Rheostats/_/N-9q0yi?Keyword=3309W&FS=True . They're also less expensive. I've started using these since they fit perfectly and I think look better than the 3296s.

The ones on the 2285B are about double this size.. .610 compared to .345. The pin spacing is also off, .350 to .197. These OEM pots are beasts compared to the small ones on the 1030 or the 2226B I've worked on.
