Try slowly opening a knife switch with 100 VDC and watch the fire ball. With care you can sustain a very nice arc, right up until it melts down into a puddle.
My bleeder resistor is hard wired to test probes. When you make the connection to the charged cap, jam it on there and leave it for a few seconds. If you pussy foot around with it you can draw a nice arc, especially if there are bus bars in close proximity to each other. The ringing in your ears will help you remember to do it the right way the next time.
I have big spring loaded clips and they are soldered to some speaker wire and 2 big resistors. Don't remember what value they are but I'll find them and report back. I got shocked.... ONCE.... I was troubleshooting a radar system and I haven't done it since then, 1983. The High Voltage Power Supply got me. The DC blew a hole in my thumb. If you get a Safety Violation during training you fail the module and have to redo it. So, I put the unit in standby, calmly walked out to the smoke pit and then I screamed. Smoked a dozen heaters and went to the enlisted club for a dozen beers. When firing up an amp for the first time, I still use earphones. I hate things that go KaBoom when you when you aint ready for it.
