Precision Tuning
VERNIER DIAL CONTROL KNOBS
A vernier dial control knob will provide smooth and precise
tuning for either a potentiometer or variable capacitor.
Planetary drive provides 8 to 1 ratio, allowing for very fine
adjustment of standard controls. The metal dial plate is cali-
brated by etching and paint filling on brushed satin finish for
a very attractive appearance. Knob is calibrated over 180
degrees of turn, reading from zero to maximum setting by
clockwise rotation. Fits standard 1/4” control shafts and
mounts on surface of cabinet or chassis. Very useful with
any circuit where fine “tuning” is going to make life easier.
