A local shop has a neon sign in the trash. 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.
