I assumed we should be past the technical level of driving a tetrode
in zero-bias with a voltage doubler on the screen by now Colin.
I would think real "experimentation" would be building a clean
amplifier that is properly engineered or even learning how a PA
works, instead of trying to drive a tetrode tube with zero grid bias
and apply screen voltage through a voltage multiplier from the RF
source.
If someone can demonstrate why this is a preferred and reliable
way to produce a clean state-of-the-art SSB amplifier, and
demonstrate why it is good engineering, I'll be all for the DAF.
Any takers? Tell me what makes it "well-engineered".
