Thats why G3SEK had to develop those excellent tetrode boards before WW3
started in Europe from all the crummy signals.

The exciter should be better then any linear as IMD is worsened by the
amp.
By the way, no European manufacturer ever used triodes for RF amplifiers
except before the time tetrodes were invented.

The 3CX1500A7/8877 and 3CX800 are indeed fine / best of breed SSB linear
triodes, but tetrodes have their own following with RF amplifier designers
and users.
## agreed. Look no further than " ssb systems and circuits", written by
a
slew of collins engineers. They just love grid driven amps..and just
hate
GG triode amps, the rational being that the xcvr has to be as clean as the
GG amp, or imd results from the xcvr.
