Some of the stuff I'm still working on, 30KHz to 500KHz 200W amp.

20W Class A Preamp driver, Broadband non-isolated and isolated Phase Splitter, and 200W Brick unit here. I can't really qualify it for full 200W because the meter goes to 150W, but I believe it will go close to 200W peak power. It's probably not 200W throughout its useful bandwidth, but I'll have to see where this leads me, it should prove to be interesting. I'd like to see this whole thing setup as a finalized amp, sweep it, and see how it measures up.

I was playing with the amp a little last night and set part of the wood base on fire! XD heheh. Gotta be careful with this RF energy now that its getting to big numbers!
What I thought was interesting here is that being driven from a coupling loop, the TC secondary is absorbing a particular amount of energy and at a critical point, forces the driving loop into heavy compression. I want to study this saturated mode a bit more further down the road. Also I want to make a horrendous power amplifier right now.. heheheh. The one I have right now is 2 pair, and I want to double that! Should prove to be very painful when it comes to RF burns.
I would also like to further investigate something very interesting, the coil's particular frequency is 256KHz, but driving at 175KHz causes a harmonic emission at 256KHz with a peak much greater then the source peak. I can't really do much about it now because the amp gets very hot within my time limit, but hopefully future improvements will allow me more time to play.

Now, 200V.

Ppp

It appears, one string in that 200V picture went off the view of camera. No load, but man was that a loud bang. I have shot marbles at 200V and they made a mark in my wall 7ft away, at a 45 angle, then the bounce off the wall, and hit my desk.

32 camera capacitors, charged to 150V...discharged to a small peice of foil, on 2 copper contacts, in the PVC pipe..most shots here had a marble being fired.

Guess I get 2 in the row..Use to be busy here! Got the mail today :P

1260221109 1643 FT6000 Caps

Got them used/pulled from BG Micro, 4.45 each. 450V 2400uf. Not tested yet but they all seem to hold a 12V charge for a very....very long time.

I always wondered what ten thousand pennies looks like, I guess it has to do with my obsession for ridiculous numbers:


1261077780 902 FT6000 10000 Pennies  [br


EDIT: I did a little weighing, and these things LITERALLY weigh as much as they are worth: they weigh 61 pounds, they are worth 61 pounds - I love the way numbers work out!

I had one of those explode overhead once, had a nice glass shower, however the main filament remained in place blasting me with an intense white light, which caused me problems when I was trying to find the switch to turn it off! :-/

Im looking forward to that, cause this thing looks awesome. Do you use some thin liquid or is that just plain air?
