I suspect that was a marketing decision, not an engineering one. Some
hams want only Eimac tubes and will not buy anything else. especially
in an amp that costs an arm and a leg like that one does.

Really? I had a Palstar 5 kW tuner for a couple of years and it worked
fine. Nothing burned, nothing melted, nothing exploded. Of course, I
was running ONLY 1500 watts.  :-)

But it was RTTY.
