Yamaha CS80

Hi,

I've just adopted a CS20M, and am having a hard time finding a few 
replacement parts - the black slider knobs and white buttons. I also 
need to replace one slider pot itself, but it's soldered directly onto 
the board on the CS20M so I'm not in such a rush!

Has anyone found a source for old Yamaha synth parts? I think the 
slider knobs are shared on various models, including the CS80.

The synth is a blast - I can't imagine how much fun the CS80 is!

Thanks,
Jeff
