[Amps] Bill Orr comment

The 3-500Z does it when the anode gets 4KV, otherwise its current is the
limit.
You are right with the 8877.
It all depends on the type of cathode.

Depends on how much of a quack your resident guru is.

A 4-1000A will certainly fit that criteria as well as a 3CX1200. The 8877
wont and neither will a 3-500Z, at least by staying within ratings.

The 3CX1000A7 in my 2M amp is right at 2.0

Have you seen a possible pattern here?

If it sounds like a duck.......
