➭Check the channels one at time to determine which is right (note: if you
have a spare amplifier module that you know as right, use it).
➭If you have determinate that the problem is a short on a rail, you must
check the output transistors.
To determine which transistor devices are bad, use a soldering iron to lift
one leg of each emitter pin and measure the emitter-collector resistance
on each device. Unsolder and lift one leg of each base pin and check the
base-collector resistance of each transistor and replace any that measure
as a short.
If all the transistors are OK, unsolder and lift one leg of each diode and
check them.
Check the circuit board for open foil traces.
Use the Multimeter as Ohm-meter to check the resistors, particularly the
base and emitter resistors of damaged transistor.
➭If the input sinewave appears to be distorted during the negative cycle,
you can assume that the problem is located somewhere in the circuitry of
the positive low rail.
If the positive cycle appears distorted, you can assume that the problem
is in the circuitry of the negative low rail.
➭If the high rails appear distorted or are not modulating as shown in figure,
then the problem probably exists somewhere in the circuitry of the respec-
tive (+ or -) defective high rail. Refer to the schematics.
