Base fed VTTC experiments

Thought I'd get the ol' Gu81 valve out and do some more VTTC experiments.  In this video I experiment with different chokes, output coils, feedback and with & without a grid leak to see what gives the best result.  Also I try this running the circuit on 2100 volts AC and 5600 volts DC to see how it performs. This way I can find out what coils give the best results, and how much feedback I need depending on what output coil I'm using and what voltage the circuit is running on. Schematics ARE in the video at 1:04, 5:22 & 14:09. So open your eyes, look and stop asking me for schematics. You are welcome to take a screenshot and copy them.

I also included bloopers at the end!

Note, this circuit is dangerous since the B+ is connected directly to the output coil, do not try this at home unless you know what you are doing and understand the risks involved.
