Hi John,
the idea here is to use the tradition differential topology which has a single CCS connected to both cathodes. The circuit I came up with gives you that but lets you adjust the voltage offset for each cathode separately so you can tweak the stage to get the same voltage on each plate. This lets you do a PP parafeed without ANY capacitors in the output stage AT ALL. The PP OTP connects directly to the plates, the primaries are connected directly to each other, no cap. This "center tap" is not connected to anything either. Because the idle plate voltages have been adjusted so they are the same there will be no DC current flowing through the OPT. (well nothing is ever perfect, there will be SOME current through it but it should be less than 1mA and Mike has stated that this should be no problem)
It gives you the advantage of a true differential stage without any capacitors either in the cathode circuit or the plate circuit.
With a true differential stage you don't need a phase splitter, the differential topology will do that just fine.
