As mentioned before I have a 4 board ENI RF amplifier for plasma generator.
So far I have taken one board out and drawn a schematic. It is a very simple
class C amplifier with feedback from collector to base for some stability. I
have inquired with a company selling these used/refurbished but gotten very
little information that is helpful. I still do not know what the main solid
state components are FET or transistor.

Gene,
I don't know if this info will help much, but the used ENI plasma generator
boards I purchased a few years back had transistors labeled ENI-21 ,or
something similar on them, and those parts were made and labeled for ENI by
Motorola.
I believe their direct cross was the MRF448, which was a NPN slilcon 50
volt RF power transistor that worked really well at 13MHZ.
