[CASIO] [CT-605] – [Seeking Replacement Tempo Fader]

Hey y’all,

Seeking a slide potentiometer with the following specs, as used on the Casio CT-605 and the Korg DW-6000:

Resistance: 1MOhm

Physical length: 45mm

Travel distance: 30mm

Taper: Reverse Audio (C)

Gang: Single

I have reached out to a few different places (including Syntaur) and unfortunately no dice, beyond buying a whole PCB from the Korg model to desolder the slide pot from. Does anyone have a suitable replacement part? Thank you!
