Amp produce good audio on all channels.I get no DC on the outputs.
If i connect a speaker on anyone of the channels the outputs start to heat up with no signal applied . If i just let it idle with no speaker connected it does not heat up Any idea where to start?

The may may be oscillating. Did you look at the speaker output when you have speakers connected?

Does the idle current increase when you connect a speaker?
