RE: To make a comparison shouldn't he be using a 1:1 IT?

Unless the galvanic isolation of the 1:1 has strong value in your circuit I just don't see that this approach has much to recommend it. Especially if it is an airgapped 1:1 interstage.

Most airgapped interstages have a distinct lack of adequate primary inductance to do the job well.

better if you need galvanic isolation to go with a parafeed 1:1 interstage. They can be built on a smaller core (with fewer turns and much less winding capacitance) and have far, far greater primary L. And remember that it is the paralleled reflected and inductive impedances that serves as the "load" for the tube driving the primary of the IT.

And if you don't need the galvanic isolation LC coupling provides even more benefits than IT coupling.
