VTTC "Losev"

Hi all.
I have been looking at the possibility of making a mini VTTC for the "geekfest" in a month's time.

So far the plan is to use a single secondary but a dual tube (probably beam triodes) setup as these can be had in 15KV variants for about £10 a pair.

Can't handle much current but should be good for demos with care such as wireless power induction and other "Fun Stuff" (tm)

Seems that 13.5 MHz is a good band to use as its ISM and in theory no license is required IF power is kept down and monitored to ensure EMC compliance.

This band is also used a lot for vacuum tube based plastic induction welders that are used for sealing bags and other industrial apps.
