 Some bits to consider before asserting the power stage has a gain of ~1...:)

1. The power tube connections are arranged to maintain a constant cathode-g2 voltage. The g2 is connected to the plate on the other 'side' or phase.

2. The primary coil is equally divided between cathode and anode load in two CT'd pieces. One CT to ground, the other to B+.

cheers,

 While I'm not the guy to do it, I suspect a rigorous and correct analysis would be had in calculating the gain of each stage and circuit and using superposition. Again, I'm a hack who understands a few things (and probably understands less than I think) and NOT an engineer.

 We're only paying attention to the power stage for the time being...:) The analysis will not take an engineering degree to understand.
