Ok... you need to find out how much current is being drawn into the
Triton. After all that work, I think the current limiting circuit in the
power supply is either set too low, or it has a problem.
Those rig are pretty notorious for drawing more current than the PS is set
to deliver - especially in a HOT RF environment (poor grounds).
Look to the Power Supply.
