Default 6C33 OTL Circlotron

I am planning to build an OTL Circlotron. This is the input driver stage. Well, really this stage can be used in a push pull Amp.
I would like to listen your comments and suggestions to improve this design.

Personally--And, its just my opinion....

Too complicated, too much sand for no obvious advantages...

A straightforward gain-stage, maybe MOSFET loaded, then concertina phase-splitter done well is hard to beat....
--Simple, easy and a good performer. Why complicate the wheel!
