STEP B : Turn on the amp’s power.
STEP C : While watching the current
(amp) meter, slowly roll on the Variac’s
output voltage knob. The amp should turn
on at about 45 volts.
When you get to about 60 volts you don’t
want to see more than a few hundred
milliamps. If the current meter reaches
anywhere above half an amp, roll the
Variac
back to zero, shut everything
down, discharge the caps, and look
for the error, short or bad component.
Correct the problem and repeat until this
test passes.
STEP D : Once you can reach 120 volts
drawing less than half an amp, you are in
good shape.
NOTE : If you don’t have a current meter
on your
Variac
, remove the fuse from the
amp, and with an amp meter across the
empty fuse holder socket, turn on the
amp and perform the test above.
