1280 replacing faders (slide pots)

The faders on the 1280 console are one of its most fragile electro/mechanical components, considering the amount of use they get and the fact that the potentiometer body has an open slot that invites all sorts of dust and moisture.

​

You can see pictures of the condition of some corroded faders and the wear and tear they accumulate with time here. "Cleaning Faders"

​

The original faders installed in the 1280 are:

​

Manufacture: ALPS (Japan)

Part No: 79G-10kΩA

Resistance: 10kohms

Taper: Audio

Dimensions:

I could not find anything within the catalog of the most popular manufacturers that would exactly fit. The travel distance of 60mm is a format that apparently is not used often on a large console format, it may be used on smaller equipment so it is difficult to find variety through the usual distributors.

​

ALPS does have a part with the same travel, resistance and taper, but it does not have the same lever type.

​

Matt found a potentiometer in the Bournes catalog that fit all the specs with the exception of the distance between bolt holes as you can see below.

Part Number: PTA6043-2015DPA103 (mouser link)
