I tried to reseat both ends of the power cable but problem still exists!! as soon as I turn on the amp with both ends connected the PS HV/Supply light turns RED!!! HELP!! Ted K2QMF Disconnect the power (red and black) cable between the amp head and the power supply and turn the amp on. Is the "HV" light on the power supply still RED? If so, the power supply is bad... send it in for repair. Dr. William J.
