It's been more then a delay for me to post this data!  I honestly can't remember how asked me but here it is anyway.

[altrez]

what AWG is that wire? stprue And what type of Toroid?

-Altrez

[stprue]

The Toroid is the standard 1 inch 5-$1 goldmine and as for the wire...

Pick-up=30 guage mag from RS

JT wire=28&26

@ Hazens1

Please elaborate on your 1K JT idea

On the bottom one you will notice crossovers.  I also have crossovers on the sides but I wasn't sure if I need them across the bottom as well.

Hi stprue. Very nice.

You cannot avoid the crossovers when you are winding the coil back down after you wound it up. Each wind down has to go over the one coming up from the bottom layer.(otherwise it cannot make its progression back down.)

I try to keep my crossovers in the inside. I only do this because when I heard the winds count on the inside of the toroid more than the outside, I figured if the cross is strong (or weak) it would be amplified if I keep it all inside. [If it is weak and it hurts things, it should show up as a problem easier if I keep it consistent.]

very nice.

I see a metal cased transistor. Is that a 3055? Are you going for extra high voltage too? 

Good job,
