I'm trying to find out if the potentiometers on the front panel of the Etherwave are linear or log taper.  Unfortunately, my multimeter is dead, so I hope one of our circuit gurus might just know the answer off the top of their head.  I'm looking for some replacement pots, hopefully with slightly deeper mounting screw shafts and would like to match the original specs as closely as possible.

Pitch and Volume Tuning: 5k lin (Mouser Stock No 31VA305-F)

Waveform and Brightness: 50k lin (Mouser Stock No 31VA305-F)

The same exist with a longer shaft (1.32" instead of 0.335"):
Mouser Stock Nos 31VC305-F and 31VC405-F

Take care when ordering from other manufacturers: While a "B" taper is linear in the U.S. and most parts of Asia and "A" is logarithmic, it's just the other way round in Europe!

Kind regards from one of these gurus :-)
