Anyone have a source? Has to be mini. Alps seem like the smallest.

Would also need the black metal knurled knobs (set screw type).

Extra points for an additional push pull DPDT section.

Anyone? Beuler?

I found this:

So for a 500K dual concentric log, I could "linearize" the second section using a 60K resistor between the wiper and the top (full clockwise position) connector. This will produce 20% less current flow than a 50K linear but should be acceptable for the Roland voltage control.

Does that sound right to you guys?

Thanks

adding parallel resistor network as described above is an acceptable functional compromise.
