Hi all, it's gren's time to liquidate again!

So...

30mA Neon sign transformers, $35 ea. 4kV, 5kV, 6kV, 7.5kV and 9kV, pick and choose.
Two fit in a $16 flat rate box, and they're good up to 150VAC. ==== Link2

90mA 9kV NSTs - $60. They're bigger and heavier, but more current! Needs UPS shipping, but should be <$25. ==== Link2

15kV 30mA NST - $100. The big boy, does fit in a $16 flat rate box.

2.25" tritium lamps left over from the last sale, $25 ea. ==== (crappy pic) Link2

PMT, for nuclear scintillation and what-not - $35. ==== Link2

CM200 half bridge IGBT, for DRSSTCs - $55 ea. ==== Link2

2200uF 350V caps, $110 for the whole box. Coilgun anyone? ==== Link2

13.56MHz center band 250W RF amplifier, for RF lasers/plasma/amatuer radio etc. Good from 6Mhz to 18. $180 ea === Link2

13.56MHz generator + preamp board, $50. ==== Link2

140kV!!! high-frequency transformer. 400V in, fusor-power out. $160 === Link2

Small 5kV (20kV+ under oil) HF transformers, no diode, for plasma fun. $20 ea ==== Link2




--Now for the cool stuff!--

6ATM Helium-3 neutron proportional counters, 1" * 18". - $2500 each. Spendy, but 5330 Barns! ==== Link2

10 to 15W Nd:YAG CW diode pumped solid state lasers, with acousto-optic modulator (15ns min pulsewidth!).
These babies are awesome as is, but if you're feeling daring I'd love to see them put out 6W of green! Have two - $1500 ==== Link2

1.5W Green laser, from a harp project that never got finished - $650. ==== Link2

Agilent 54624A 100MHz 4 Channel Digital Oscilloscope + Pouch, Manual & GPIB interface. A real scope, not some china POS. - $900. ==== Link2

Agilent 33250A 80MHz Function/Arbitrary Waveform Generator, for waves and such - $2500. ==== Link2

180kV full wave, open-air voltage multiplier. Glassman. - $700 ==== Link2

200kV super-fancy stainless steel current and voltage regulated electron-microscope worthy awesome-plier. Made by TDK lambda. - $4500 ==== Link2

160 * 320 60Hz thermal camera, composite and LVDS out. Programmable histograms/firmware. $2500, or $1800 for another one with some bad pixels. ==== Link2


Payment for large things can be arranged via paypal or postal money order, but for the smaller, sub-$200 things I prefer google checkout.
(All you need is a debit/credit card to pay the emailed invoice). Or, if you distrust paypal, GCO can be used for the larger items as well.

Have fun shopping! If you'd like to make an offer on anything, just ask.

-gren.
