New Old Stock Allen Bradley (A-B) MODPOT type miniature potentiometer, model number 20M277, dual 25K elements, 1/8 inch shaft concentric with 1/4 inch shaft driving independent variable resistors, has wire leads for PC board mounting (you can solder leads to these). These were used in Watkins Johnson receivers, straight from WJ ! NOTE: These are all LINEAR taper (the "U" on it indicates LINEAR taper). I actually have the white WJ knobs that fit this for sale
