you are going to get poor balance without one. you may as well hang up the idea if you aren't willing to work with a CCS.....the inbalance will color the sound to much and not give a good representation of PP vs SE.
I don't think there is a cookie cutter EL84 driving EL84 push pull schematic out there for you... you may get away with an EL84 driver into an inter stage transformer.

While am proponent of Ccs ... A transformer phase splitter walks.all over it.

IDK about that...LOL As a matter of fact I come to the opposite conclusion. What TX's in particular are you using? I might have to try them.

Magnequest... Cheap won't do in this position.
I don't like interstages but perhaps that mantra is correct "good ones won't do... You need great ones"

EXO 173... That was it's only real purpose. Phase splitter... With 180 degrees and er , no phase shift.

That one I am intimately familiar with. While I discovered it can test well, I was not fond of its sonics( in any of implementation ), especially in favour of a LTP riding a CCS.

Understood, preferences are as multi-faceted as light through a prism.
A very close friend has owned Wilson Watt 7's for years and I never liked them as much as normal Khorns. Polite, clean, accurate.
No jump factor.

Guys, keep firmly in mind the fact that an interstage trafo inside a NFB loop is a prescription for trouble.

I have grid chokes in the last two 'ground up' E-Linear builds...:)
Have to get some for the next time I go playing with my W6m's too, along with a lower voltage power trans. Going to take B+ beneath 400V on that one.

I am breadboarding a 12at7 driving el84's in PP right now just to see how the PP compares to the SE. No CCS required. I may not go any further than that with the PP design. Depends on what I hear.

what circuit vinnie? are you able to take distortion measurements?
At this point I am just trying to get it up and running and listen to it a bit.
