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.
