RE: One of the problems with this design

I think that all BAT 6c33c amp use typical plate load OPT coupled rather than Circlotron circuitry. and VK75se is completely no global negative feedback from 1st stage to final(To my understanding, Circlotron utilize output tube cathode to connect opt, correct me if mistaken)
The VK-60 uses an output transformer in a Circlotron output circuit. It is not a 'typical plate load OPT'.
