I would use an input bridging transformer to split the phase, such as Jensen, Peerless, UTC, etc... You get balance input and not have to deal with DC on the primary, which makes it much less technically demanding to make, and you get perfect phase splitting for push-pull. And it's cheaper than an interstage transformer.
Yep, thats the best approach.
I would then go LTP all the way to the OT.

Re: Hammond T-125E - Paul Joppa - Bottlehead Forum
I've got this on my breadboard with the Hammond 125e, using the Audionote 300b IT cct first stage with 6au6 ( 6au6= 6sh7 dif pinout) 180 volts.

I've tried 6v6, 6y6, 6w6 all triode mode and triode 6s4a all SE. The best sounding were the 6w6 (22mA triode) and 6s4a. I have not yet tried the Allied IT in PP-yet.

EP Phase Splitters
Hi, Do you still have the EP iron?
Thanks
re:EP - got a pair of those unused
