Original poster: "Jonathan Peakall by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jpeakall-at-madlabs.info> Greg, All, I got burned by those caps too. I have tried 'em for a bunch of things, and they blow instantly. I found that some would blow at less then 7kV. Upon disection they proved to be full of air bubbles and crap. Oh well!
