Audio Systems: how can you tell, output transistors, amp output

Question
How can you tell if your amp is blown?

Answer
Easy.
ONE:  Disconnect all loudspeakers from the connections on the back of the amp except one.
TWO:  Using music program from cd player or radio, check for sound coming from the speaker.
THREE: Then, move the speaker from one amp output to the other thereby checking each one of the channels....

The speaker you are using for test must be a good one with good wire, also.

A common failure in audio amplifiers is blown output transistors. They are quite expensive to replace. This failure is most often caused by overpowering the amp OR a shorted speaker cable/wire.

Let me  know if you have another question.
