Hi,
Cool schema. I'd have to study it more... I posted a similar thread below... It's basically a circuit posted in this forum before by the on hiatus Thorsten Loesch. The Parafeed L-inverter here has 2 CT connections to be able to use a 'bias balance pot' to balance current via some postive V on the DHT grids. I wonder if Mike cand do something custom like that for an L-inverter. Anyway, a buddy told me that I could use a high quailty 1:1 transformer for a parafeed L-inverter but I dunno what that really entails technically.
BTW, for C1 in your circuit, you could try Damped Resonance Parafeed (DrP) by VS. You could use a lower value high quality parafeed cap and the Drp cap could be lower in quality like mylar and a carbon comp in series for damping LF resonance.
regards,
fred
