Robb,
Yep, your right...got em cornfused...
I had the Centaur for 6 monthes...worked OK...got a Collins
30-L1...SUPER.
I still have it, and a Alpha 91b, and the great Drake L-4B (I recently
restored the PS and rf unit)
Yep...for some reason I got Centurian and Herc confused.
The Centaur was OK...but a Collins 30-L1 is much better.

Lee,
You are thinking of the old 444 solid state amp. The 411 Centaur uses
3x 811A
tubes. TT states on their website that they can no longer repair the
444.
Concerning the history of the 422..the original model had Eimac 3-500Zs
and the
tubes were biased "On" even in standby. TT later offered a mod to
change the
bias circuit and added this to later versions. I have done this to a
friends 422
along with new black panels/case to match the Orion.
Just sold my 422 to make way for more Elecraft equipment, great amp.
Know where
a 422 is with Eimac's in the local Colorado Springs area that is for
sale.
Also have an L-4B with the original tubes, still get full power and
another
great design.
73,
Robb N0RU
