This thing: Cute little cap charging power supply, good to 1500V, brand new with manuals, connectors, etc. Inside is a half-bridge of IGBT's driving a ferrite transformer. There's some speculation on fusor.net on rewiring these to give higher voltages; else these are good for charging coilguns.

Just noticed 2 kinds of relatively inexpensive energy discharge capacitors on ebay. You can get either type for $200 and free shipping (in USA) from "thepartscrib" or $20-$25 + freight cost from "liquisinc". Both sellers are dealing from the same stock.
GE 30F1666 250 uF, 10 kV, 12.5 kJ, 137 lbs Maxwell 36203 nom.460 uF, 8kV, about 14 kJ, 144 lbs.
Also, what does everyone think about this item It seems like it act like a variac, I asked and it is AC to AC, so what does everyone else think?
EDIT: I tried looking this up and I think it may have something to do with changing the angle of conduction for the thyristor
EDIT2 : After asking Sulaiman, he said this is *ok for resistive and resistive/inductive loads but not for capacitive loads, and lots of RFI would be created unless carefully filtered*

I do not see anything against listing your own items here. So: My ebay username is >>> Juniortore1 <<<,
and I am hoping to sell five items to fix my paypal balance of $2.14 --------------------------------------------
---------------- I have one hair dryer motor for sale (can be used for a medium sized van de graff generator)
I have one groove2 laser diode driver that I did not need that I am selling.
one small 7200RPM motor (works with about 3-7 volts with my experience with other motors of the same
10 small neodymium magnets harvested from a few DVD burner sleds (goes with my laser hobby)
And Hopefully the biggest item that you may enjoy... a 48A 500V IXYS mosfet. Last I checked on google shopping, they were 46 dollars each. I am selling it for only $35
