Unfortunately, I don't have a picture of it, and I got rid of it a while 
ago when moving offices.  It was a black cube roughly 8" on a side, and 
weighed in at 80lbs or so.

I *do* have a few 60mA, 48kV x-ray transformers laying around though.  
Those suckers are heavy (>100lbs).  I made some nice long plasma 
streams with two of them hooked up out-of-phase giving me a >120kV peak 
voltage, before I melted a current-limiting inductor in one.  At some 
point, I need to rewind that coil (it's only got one layer, so it'll be 
easy to do once i get some magnet wire).
