i know very little about these amplifiers, other than what i read in the tutorial, that they are different.
here is the drive signal. The problem is no audio, current draw is not even registering on my power supply's gauge.
This is the drive wave on the pads.

One of the mspa56 transistors was failing intermittently. when i first tested regulated was present +-15vdc then just now it was missing?
So i replaced it and it is now drawing current at idle., but i has the 45vdc on the speaker terminal. i pulled both outputs and tested them both were good.
