Heat-Damaged Bass String?

[Don]

Hi David,

The shank bending pliers that I recommend the incandescent dimmer switch
for (NOT MOTOR CONTROLLER) draw 150 watts. I agree they should not be used
with a heat gun--but for different reasons. You may well burn out the motor
on a heat gun with such a dimmer, which uses a silcon controlled rectifier
to switch the A.C. into pulse D.C. and reduces the voltage by reducing the
number of pulses.

A side benefit of using an SCR on regular incandesent bulbs is that they
will last for years longer with pulse DC rather than A.C.
