Thanks that was one of the missing pieces that I need to know THANKS

a 15K ohm pot 270 degree linear taper is 5K at 0 to 90 degrees.

270 / 60 = 4.5 so for 60 degrees you need 22.5 K pot linear taper rounded to 25 K.

I am playing with a 25k liner and will try a 30k

That is exactly how one of my cheaper pot boxes is made. It is a 15k pot and the box has hard stops limiting it to 90 degrees of travel. It works okay but I've decided to go to a HEPA input instead.
