MC-202 Decay Slider (1Ma)

The Decay slider has died on my MC-202, it looks to be a 1Ma value and cannot find it anywhere. All the other slider are readily available from a few sites, just no 1Ma.

With the Decay slider dead the Sustain slider isn’t working either, although by shorting the Decay it allowed the Sustain to work again. Wasn’t able to get any reading from the Decay multi-meter either, so it’s definitely got a broken trace.

Any ideas where or how I can find one?
