Voyager Old School keyboard problem

[Cello]

Hello and greetings from Switzerland, i‘m new here

My Voyager Old School (SN°272) is causing problems
The top key has contact problems. Cleaning has helped and it works as long as the keyboard is not installed.
I know that in Old School another keyboard was installed in addition to the Fatar keyboard. But I don't know which one at the moment and in my synth…
I am looking for replacement contact rubber bands for this one and/or the Fatar keyboard
Can anyone help?

Welcome to the Moog Forum, Cello!

Maybe ask syntaur.com. They got contact rubbers in three length online:

They also got a tech forum:

Or even better: ask Rudi Linhard in Germany. He is also in this forum as "RL".
