your solution would then be at your nearest Audio Repair Shop repairing amplifiers.
what seems to be the problem you are having with your amp?
is it having a power or none at all?
will try to look for the web site of your amp, but maybe take some time might as well include the model and chassis.
typical cases is the power transistors going bad, and the amp
producing no power at all to the speakers.
some may just be a resoldering of cold joints, if you have a multimeter , that would help a lot determining where might be the
trouble you are having. but i don't recommend you do these unless
you feel you can do.
the amplifier will show protect if the power supply is good, of course
there will be no light indication if power supply is bad.( MOSFET)
you just need to measure each speaker out voltage, whichever
produce an over of 0.7V is bad, you can use 12V bulb for a tester
if you don't have a multimeter.
if the bulb lit or lights then most probably your amp channel is bad.
if you don't want to replace or still waiting for parts , you can still
use the good channel of the amp., only if power supply is good.
all of these can be done with a help,
