Vishay PRV6 has the best torque I've experienced so far. Good for bigger
knob. They are little 1/2'' thingies with only 3, 4mm and 1/8'' shafs.
Also Bourns 51 has good tourque sometimes, and the word "sometimes" is
the key here. I've had them loose and stiff from the same batch like
they were was totally different products.
And TT P160 is not that bad either, although the most loose of those.
Very stiff torque has Telpod CW18, you can get them via TME if it serves
your country. Probably the toughest of all. Also SP1.2 from Telpod,
large bulky pot for tanks, similar were used in Polivoxes. The size of
the A-B ones from old moogs.
