Akai S1000 / S1100 samplers

Hi,

I use an AKAI S1000 Professional.

I've broken the volume potentiometer stick.
So the vol pot is completely out of order.

I need the Entire replacement part, the pot, with the stick and the
plastic knob.

If someone have a salvatage unit and can pull the part off,
please contact me!!! 

Thanks a lot!.
