Ian,
If you could list the top few important parameters to low distortion tetrode
sign, what are they? I think most of us know the importance of
well-regulated screen voltage. Other top factors?

By the way, no European manufacturer ever used triodes for RF amplifiers
except before the time tetrodes were invented.
Thats why G3SEK had to develop those excellent tetrode boards before WW3
started in Europe from all the crummy signals.

Not quite... I originally developed the Tetrode Boards because of all the
crummy signals from 4CX250Bs!
The differences between triodes and tetrodes are far less important than
the differences between individual amplifier designs, and the ways that
individual people try to operate them.
