Original poster: "David Huffman by way of Terry Fritz <twftesla-at-qwest-dot-net>" <huffman-at-fnal.gov> Who has stacked up a bunch of 1N4007 to rectify NST outputs? Just wondered how many and how well they work. I would like to full-wave rectify a 15KV NST for maximum output voltage. Do you have to add C's and R's to the stack? Dave
