Simprop 2+1 stick/trim pot

[stuart mackay]

Anyone got a pot that can get my 2+1 working again please?

What value, 5k?
Have they failed or just dirty?
They look specialised , have you any separate trim pots you could fit then you could use individual ones.

Maybe something SLM used to make would fit.

.....actually tandem pots are quite common and can be find as spare parts for old stereo and similar products.

Thanks Chaps for suggestions, will strip it out and have a closer look regarding cleaning and sizing.

Just be wary of ones taken from old stereos, as quite often they are logarithmic, and you really need linear ones.

I've actually got one of these stored away somewhere. It was a long-term project, and I was intending to replace the stick units on it. I'll see if I can find it and if it has the same trim arrangement.

Its not in good condition, so they might not be any better than yours! Have you tried a good shot of switch cleaner, followed by a good "wiggling"?

OK, mine appears to be the same! It looks as if the arrangement is co-axial shaft(s) to the two pots. Mine is in not such good condition, and the hinge at the back has rusted almost solid! I'm currently soaking it in penetrating oil, but I'll probably end up drilling out the pop-rivet that secures the hinge.

Once I've got it apart, it will probably be easier to send the complete stick units.

PM me your address, and I'll get them off to you. Probably won't be until tomorrow to give the penetrating oil chance to work!
