Default Re: 807 tube amp, any ideas?

Ultra-Linear is sort of part-way to triode connection. The screen follows a percentage of the anode swing. For triode connection, that percentage is 100% for tetrode operation it's 0%

For ultra-linear operation, different people have pinned the tail on the donkey at various percentages. The tetrode end of the range (0%) tends towards more gain and more output power. The triode end of the range (100%) tends towards lower distortion at the expense of lower power and lower gain.

Can't afford the volcanic island yet, but the plans for my monorail and the goons' uniforms are done
