True, but then you missed the underlying irony... it's also a tube good for
serious frying of beginners... speced for 10 kV and 15 kW it may _NOT_ be the
optimal beginners tube if tossed the appropriate power. Self-oscillation in that
one may also be objected by local authorities... ;O)

None of the other proposals where very "normal" in this respect.

Well, we have to work on this one, don't we? ;O)
