Patrick was speaking of legalities. I'm sure all of us here, know how
to load a rig to a kW.
What he's asking is:
How do we go about getting our old '1kW DC Input to the final' rating
back from the Feds?
And, as noble as that sounds, I'm afraid that you'd have a better chance
of picking up a 250TH
at your local corner store market. You know, the one that has a
tube-tester in it?
Just like those days of tube testers in the local stores, so too are the
days of running a legal 1kW
DC input power level gone.
