Fortunately, I have too many other things to do and spend money on so a scope clock is out for me. I don't want to go near those kind of voltages on a workbench as I have no practical experience to fall back on. More power to those who can—safely. Note that over at the GeigerCounters group talking about building negative HV power supplies can get you banned. A couple of people found that out the hard way after having been warned. The -900V supplies in Geiger counters are grandfathered in, of course, and the currents are very low.
