Maybe I'm blind or something. Where is the transistor on that circuit board??

@ All

Here is my most recent achievement.  Please feel free to replicate if you wish  but keep in mind I'm sure I can get the performance to go up.

PARTS
1 Biggo Ferrite Toroid from all electronics or electronic goldmine
1 2N3055 transistor from RS
1 1000v bridge rectifier
1 400v metalized cap at I believe .01pF
3 2.5v 10F supercaps from maxwell
1 POT I think mine is a 1K but it might be more.

3 Base turns
15 Collector turns
both with 30 gauge mag wire from RS

265 turns on the Pickup with 28 gauge wire I pulled out of a levatron.

This coil is wound in the Hazens1 basic way.

Step 1

White stuff is plumbers tape to keep the base and collector windings together.

Wind it up!!!

Finished product.

2 20W's and I know I can get more.

P.S. When I fist hooked this biggo up I was getting 879v but after messing with it I got what you see.  More then evough to have some fun with
