Usually, phase splitters (in a PP tube amplifier) are in the stage immediately before the output tubes.
Is there anybody that can argue on a different topology: that is a phase splitter (with gain, like a Long-Tail, Schmitt) as first stage, followed by the driver tubes, then by the output tubes ?
I plan for a low impedance driver circuit, like the one on can get with a 6C45P-E loaded by a solid-state constant current source (IRF830), I circuit I have alredy used (with success) in some other my realizations.
Output tubes are to be driven a little bit in class A2.
