Custom Potentiometers in Small Lots?

[David Forsyth]

I am looking for a manufacturer to make custom slide pots of given physical
dimensions in a variety of values and tapers. I have written to various
makers and gotten no replies. Does anyone know where an individual with
some money to spend could have custom parts made? I do not represent a
company or corporation, so perhaps that is why I am getting no attention.
If anyone knows a source of custom manufacturing in relatively smaller lots
(say under 5000 pcs), I would appreciate the info.

thanks,

Dave

May I suggest you stick with what's in the catalogue ?

What's so special about what you want anyway ?

Hi Graham,

If I could find something in "the catalog" that replaced the parts I need to
replace, I would be overjoyed. Perhaps I'm looking in the wrong catalogs.
The parts I have are 30+ years old, made in Mexico by CTS and used in
vintage analog synthesizers. Essentially, they need to be a more or less
exact fit replacement. I don't even need the whole pot made up, because the
carbon track is replaceable so even if I could find replacement resistance
tracks I would be happy

I suspect I know the type you mean. It's not actually very popular any more.
Modern pots are smaller but it is at least a 'generic' type.

What's the diameter of the body (in mm please ! ) and what track resistances /
laws are you looking for ?

Do you recognise it here btw ?

Hi Graham,

The pots I am looking for are slide pots, so I'm not sure if you had the
right thing in mind (you had asked for
a diameter). I am looking for the following values:


1K Linear
1 Meg Log
100K Linear
100K Log

The slide travel is approx. 45mm

The closest part I could find in current manufacture was an Alpha pot, part
number
RA4520F-10-20D1-B13 available from mouser.com as 312-9201F-1K, however
these
come in linear only and would require some retrofitting to the original
layout.

There are some pics of the pots I am looking for in the photo album on my
ARP page at:

The pots made by CTS currently are not the right dimensions or values.

thanks,

Dave
