TRX2A Shaft 'wobble'
Posted: 19 Apr 2019 18:43Found the shafts on the AF GAIN, RIT & CW SPEED potentiometers to be very 'wobbly'. If anyone else has noticed this, here's a 'cure'.
Located some aluminum spacers on McMaster-Carr's website. Part number 94669A003, US$ 1.51 each. Six mm od, 3 mm lg & 3.2 mm id (clearance for M3 screw). Just remove the knobs, drop a spacer over the potentiometer shaft and replace the knobs. Now much more stable!
