[sdiy] slider search

[luther rochester]

I'm building my BOM order for Juergin's Polymoog resonator board, and 
I'd really like to use sliders for the controls like the original. 
However, I'm having trouble finding a source that has all three types 
needed:

3  10k dual gang lin
3  10k lin
5  10k log

I'm making a stereo pair of these, so I'm going to need double these 
numbers. 45mm travel seems perfect, but a little smaller or bigger could 
do. It seems that nearly all the dual pots I've found are log taper.

Any ideas?
