Default Bourns Pot Shafts Not Long Enough!

Another possibility is to get a coupling - a short piece of thick wall
tubing with two set screws - and couple another piece of rod of the
correct diameter to the existing pot shaft. You could cut the shaft off
the old pot that you're replacing and use that as the extension. You may
have to cut off a piece of shaft off the new pot to make room for the
length of the coupling.

Really, though, I was going to suggest what Phil did - cut a slot in the
end of the new pot's shaft to make it screwdriver-adjustable. I take it
this it a replacement for the input gain control on the Event speakers,
so it's not something you'll be changing often.


That is correct, this is the sensitivity/gain pot on the Event TR5.

Agreed, I could do that, although the pots that Digikey have in
stock are the "D" type shafts, so that would make it harder to
adjust with a screwdriver.

Plus, re-sale value is lower, when repairs are visible, and the
speakers no longer match.

I'm trying to repair the original pot now....stay tuned!
