From a DC power supply used in a plasma arc control system - two 10,000uf 200VDC capacitors (low ESR) (from digikey) CDN 382LX 658-1138 64355 - 500VA toroidal transformer STN251330 - Full bridge rectifier GBPC3508 You can take the unit as is, though for your safety I hope you know what you're doing, it just has a breaker and floats the output voltage with no ground. The components are quality though for use in other projects. Price negotiable, make any cash offer, let me now and I can leave it out for pickup, cash in the mailbox
