It fell, and the tube broke. I suppose the power supply is good. The specs are on the power supply: 7000-8000 volts output. I can't think of any use for it, and it's not as if I have room for any more junk. Is there any reason I should grab it? Exactly the right voltage for a home electric chair - and more than enough amps. Nowhere near, most NST are good for 20-30mA and by their nature are current limited, potentially dangerous, but not automatically lethal. A true statement but.... 15 mA is enough to 'freeze on' to a current source. That can EASILY happen with 110 VAC, harder with 8 KV. More likely to throw you across the room. On the other hand 15 uA across the heart region is sufficient to induce ventricular fibrillation (uncoordinated quivering of the heart) which WILL be fatal if CPR and/or defibrillation is not administered within very few minutes. Microwave oven transformers on the other hand are another thing entirely. Safety is important, and any high voltage should be respected and used carefully, but overblown dire warnings accomplish nothing. I was playing with NSTs by the time I was 10 years old, I've made it this far. -- bz 73 de N5BZ k please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. remove ch100-5 to avoid spam trap |
