You've got a small-signal circuit needing a linear taper and the old 9mm pot's giving you crackle or drift. This Jaycar 50K ohm linear (B) single-gang replacement is rated for 50VAC with under 100mV slider noise. 300° rotation, 20–250gf·cm torque — smooth through the full sweep. Drop it in, recalibrate, move on
