49 mk3 slide potentiometers replacement parts


I bought from a thrift store this keyboard, but sadly 2/3 sliders are erratic, giving random values. Hard cleaning with isopropyl alcohol (IPA) / air duster improved the situation, but still not working fine. I have the soldering equipment and skills to repair, just missing the parts.

Any ideas of the reference number of these, and where I could purchase them? They look close to some ALPS RS1, but the orange colour and marking makes me think they are coming from soundwell, which I can’t find anywhere. That 6 pins footprint is not that uncommon, but still, couldn’t find one with same specs:

  • Travel: 30mm
  • Dimensions: L: 45mm, W: 10mm, H: 7mm
  • Metal Lever: 10mm
