Resolved: (sorta)
I managed to finally get a little RF probe? to work, primarily as just an indicator since I didnt have the exact values for the diode and resistor.
Unbelievable, not having any rg6 patch cable lying around I had scabbed the big stuff from my HF rig and bulkhead. That meant using adapters to get it all connected. I found two bad adapters. One just had the inner conductor not making contact due to corosion but there was a a pl259 to BNC that was dead short. Long story short, no RF into the amp. The amp actually works, but exhibits lower power than I expect.
I recalibrated the bias voltage /current and managed to get 30 watts at 20V. at 2-3 amps. I still need to beef up my power cord to make sure that it is not limiting current but is there anything else I should look into for low output?
Moral of the story, assume nothing. Check everything.
