I’ve been left to my own devices and started looking at circlotrons. Mainly out researching CF and noise reduction.
Broskie shows a CF zen with Compliant CCS and that became inductor based, and then I thought about doing a differential circlotron with inductors to overcome the need to have a ground reference (although this ruins the idea of ground noise injection at the anode via the ground references cccs).
So would the architecture above work? I don’t see much difference to a LPF so I was wondering if a cap between the anode and ground would allow ground noise in too this cancelling at the load. (I’ve not thought this but though just now).
I'm not sure it is quite fitting the Circlotron scheme, with two primarys (assuming the L's near the tubes are primary windings). But those L's should absorb the HV AC at the tube plates. So the secondaries (assuming the L's near the ground point) are free to put a smaller voltage across the cathodes for N Fdbk. Seems like it would work. But couldn't this just use an ordinary P-P OT with two secondaries in series? No need for separate primaries and floating power supplies.
