Below is my attempt at an output wiring diagram for KT88ís and a Hammond 1650N output transformer.

Iím assuming that the screen inputs on the output transformer will not be used in triode mode.

Does this look right?

Thanks, Jacques

Yes, that looks good.

I use a 10 R resistor in the cathode to give easier reading of the cathode current as most of my meters are not real accurate in the low mv range. The 10R resistor does not give much feedback, but gives 10X the voltage for setting the cathode current.

Apples and oranges.

This is the basic bias supply I'm looking at.
