[sdiy] Fixing the aftertouch in a Yamaha DX11?

[cheater cheater]

Loscha,
I'll make sure to try that combo!
Have you got the service manual for this thing?

As far as the aftertouch sensor:
it's a capacitance strip.
Two strips of copper foil with a piece of clear plastic between them.
Seems the strips are extremely oxidized.

Actually thinking now they may be yellow cause they oxidized - maybe
they're aluminium.

Either way, it's out of question to repair it. Gotta buy a new one.

Cheers!
