BEST - by FAR : Direct Couple"


consider that when driving an IT your generator (the tube driving the primary) has to also charge the capacitances of the transformer as well as the tube must drive all of the losses (core and copper losses) of the transformer.

Measure the exciting current necessary to drive the IT you have in mind and then compare it to cap coupling (RC or LC).

And in direct coupling if the power supply is in series your front end tube must drive that reactive impedance.

I'm afraid that there is no fee lunch.
