Got a Kicker KX1200.1 amp. Amp coming on but no output. Replaced 240 ohm resistors R195, 155, 204 & 215. Replaced 180 ohm resistors R193, 194, & 169. Replaced 2K resistor R201. Replaced 1K resistor R274. Replaced Diode D118. Amp would power up and immediately go into protect. Replaced U14 NE529 voltage comparator. Amp powers up and plays good at low power output. When I crank it to about 50 watts this is what I get. It doesn't pull the power supply down. Any ideas?
