need help working on a dead amp
Ive got 2 Tsumani HQ2002S amps sitting in my room right now. Neither of them work.
On the first one, It powers on, the fans turn on, the error light comes on, and nothing comes out of the output terminals.
On the second one, It powers on, the fans turn on, the error light does not come on, and nothing comes out of the terminals.
Does anybody have a good guess as to what is wrong with these amps. I know its impossible to know without actually going through them yourself with testing equipment, but if you had 10 guesses as to what was wrong, what would they be?
would be checking voltage from power supply to amp section.
output trasistors for dead ones.
anything obvious like burn marks or discoloration from heat.
if theres no voltage from the supply, remove the rectifier diodes and test again, this should give you an idea if the fault is in the power or amp section.
