Guelph, Ontario Eh!
Looking for a part for a vintage Aphex CX-1 Compressor -

On this 500 series compressor the input and threshold are an Allen-Bradley Mod Pot Dual Concentric - Outer / Front Layer is 1M Linear for the Time Constant and the Inner / Rear Layer is 25k Audio for the Threshold. 

The 25k layer is pooched and this is what I am looking for - Neither State Electronics or Blore-Edwards could help even.  I'd buy the wafer/a pot with the wafer or the whole dual-concentric (maybe even a parts CX-1 if need be)

I've attached a pic - will reply with more but msg me if you need any more details!  Thanks!

So thought I would check with you fellas to see if any one could help - thanks!

...Already contacted State and nothing...and the 20k linear won't work but it did inspire another Ebay search and I may have found something there that might work...

Unfortunately all the 25k pots currently on Ebay are linear or reverse log taper...I'll keep looking there but if anyone has one i'm still looking!
the rear section of this:

is a 25K "A" taper (clockwise modified log taper)

Are you still looking?
I have this.....

Quite possibly!  I've ordered one that the seller says is audio taper however it wasn't 'A' marked so I'm not sure until I get it.

I'm in Canada and to order the one GridCurrent posted will be over $80...over half of that is shipping!!  sigh.

That does look right thanks!!  But damn they want $45 to ship that little thing to me (from US to Canada should be around $16...)
