-Current transformer: It seems that this is 200A, but I don't know a lot about it, so I can't really say for sure. Either 600V or 10kV according to the label, not sure which is the rating. Maybe good for watching a HV cap bank discharge? Have smaller ones too from Prius inverter and such. -Also have some other transformers. Not quite sure on rating, but they are a bit smaler than the one in the picture (they are iron core, not current transformers). Not sure if anyone could tell if they wanted it from just that, but figured I might as well mention it if someone wanted more details. -Extra capacitors include some what I believe to be ham radio capacitors of some sort. They have terminal posts and ratings like 10uF 1000V. -Muffin fans. They are maybe 4 inch and 6 inch in size with metal bodies and run at 120VAC. I believe they were taken from cash registers. Some run silent, some have some noise. -Lots of other computer stuff...if you need something, maybe I have it. Although I have server stuff, not a lot of extra stuff, so probably nothing really high end extra. I probably do want to get rid of a dual PIII board/processors though, might be worth somethign to someone. Additionally, I have a box full of old laptops. If someone wants to make me an offer for them, I'd be glad to give them to someone who thought they could use them. -Alluminum powder (1000 mesh atomized) if anyone needs a bit.
On the buy/trade side: -I am always looking for more capacitors (350V+) for capacitor bank. -Have a fair amount of SCRs right now, but guess I could always use more. -Laser stuff is always fun. I am in the middle of building an argon power supply for my Spectra Physics 163-A1A2 laser, but if someone had a power supply, I might just want to save the trouble and buy a "real" one.
