I want to make some changes in power supply, I'm thinking that can be more helpful tuning coils and circuit with final voltage, and not with the reduced one.
I tried a voltage doubler with 4x400v capacitor in series, an huge waste of capacitance, but my only way to use a doubler up to kv. Voltage without load is 1016 volt now, with load connected I think i'm in datasheet manual of tube. Hope it will give me some good results in flame stability and autofire.
keep fingers crossed for me!
