Remove the two nuts and two flat washers from the 250K
Bass and Treble pot bushings. On each pot put one nut on the
bushing, turning it all the way down on the bushing.
Put one of the 3/8" lock washers on the bushing, then mount
the pot to the front panel with all lugs facing up.
Place one of the flat washers on the bushing followed by the
remaining mounting nut and tighten. (Keep the remaining flat
washers as one will be used in the next step).
