Are all the outputs IRF640n's?

I have a BXi2006D that uses all IRF640N's. Some of their amps do and some use the 640/9640 combo.

Precisely why I asked about that specific amp.

Post a pic of the board.

If the amp used "N" channel outputs only would you be able to tell by looking at the audio driver boards drivers?

It will oscillate fine if I remove one of the output inductors. It doesn't matter which one.

If memory serves you should have oscillation on one side of the output inductor and audio on the other side with them installed.

With both installed I get excessive current draw. If I pull the final inductor making up the last filter it will idle fine, but I see no audio.
Total mental lapse on this one.....

Do you see audio on the output side of the other filter inductors?

Can you post a photo of the board?

Well if you have no audio at one terminal of the inductor you may have an audio driver board issue.
