Kurzweil PC1x, trimpot fell apart...

[PhantomBox]

Hi guys.
This regarding a Kurzweil PC1x keybord.
A few days ago I asked for a replacement for the TLC2272CP.
Today I inspected the pcb on the pitch / mod assembly once again and it turns out that trimpot R15 is missing its tiny adjusting wheel...
To all Kurzweil PC1x users out there:
Can anyone tell me the value of this R15 trimpot? Please?

You may be able to measure it between the two outer terminals on the board.
Sometimes the case is marked with the value. Or remove it first.

Well, I know. I was trying to avoid that and ask first.

Gonna have to remove it anyway.....
