Vostok 3.0 Vacuum Tube Tesla Coil Demo + Theory Of Operation

Vostok Vacuum Tube Tesla Coil in it's 3rd and possibly final form (unless I make drastic changes to the circuit which then requires drastic changes to the frame).

Currently Vostok VTTC is using dual G-811 vacuum tubes wired in parallel in a Hartley Oscillator configuration which loosely follows Steve Ward's circuit below:

The down side to this circuit as Steve Ward explains whilst using dual tubes is that one tube will like to take more load than the other, resulting in uneven load sharing between the tubes and ultimately no noticeable improvement in performance compared to the single vacuum tube design.

The way I would like to overcome this issue would be to use a similar Oscillator but in a Push Pull configuration, this way I could get twice the voltage swing over the work coil therefore a larger voltage on the secondary, but not over volt the vacuum tubes, as each tube would only see half of the supply voltage, thus evenly sharing the load.
