If the power supply FETs are still out of the amp, pull the PNP driver transistors. Does that allow the IC to produce the proper output waveform? ••• More options Share M mike49504 Member Joined 2006 2010-12-13 11:04 pm #46 2010-12-13 11:04 pm #46 I removed the 1023's from the driver board and the signal looks better .
