Aaron ,
This may sound stupid of me to ask, But do you send the high voltage AC (from the transformer)through a bridge rectifier and then send the High voltage DC into the tube as Gray states he does in the patents? If I can remember correctly the RMS Output from a transformer is multiplied X 1.414 to give you the DC output. And I don't think any transformer this includes ignition coils outputs DC current unless it has a built in bridge rectifier, or power inverter.The reason I ask is I haven't seen any vids from anyone showing this.
