Is there any chance that the 50V heavy gauge Red/Black cable is not firmly seated? The 75A Anderson Power pole connectors require a good firm push to seat completely. I've heard of a few cases where the connection was intermittent because it wasn't completely seated.

Ted,
Make sure the large red/black cables are pushed on all the way. You should feel a double click. If the light still is red suggest you contact Elecraft support.

GREEN!! 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.

Sounds like one of the LDMOS devices may have let out the magic smoke.
Contact support so they may properly troubleshoot the issue with you.
