...DC voltage across the emitter resistors. If it's more than 0.001volts (1mV), reduce it to 1mV. The output transistors MUST be clamped to the sink when setting the bias current. Recheck the biasing ...
...output filter inductor in the amplifier. You should be aware that the speaker outputs of the amp are biased at ~40v DC and can give a good shock if you touch the speaker wire while you're grounded ...
bias current) of the output section is set at the lowest point that will prevent notch distortion. Setting it higher will only make the amp run hotter. It has nothing to do with the protection circuit
...bias or dc balance alighnment thats needs attention. Always take care of the smaller problems before they grow as this problem could grow to where it pops your outputs , your speakers or the drivers. ...
DC bias and offset on the outputs too, to make sure everything is OK there. In short, you will most likely need to go to a repair shop that can do all this and who would know what the heck I'm talking
...outputs use .6V as the bias differential. Check for DC voltage on the inputs to the transistors. These are standard designs. I'd check for DC anywhere along the signal path. Dan TRANSITOR CLIP ...
