Â*Â*Â*Â*Many common TO-220 devices will work, like a TIP-41C or a BD-911.
You may have to put sleeving on the leads and twist them around to the
correct hole, depending on the board.

Ok, I'll try it here too. I posted this in another group and finally
reluctantly shared what it was for to be met with almost instant
criticism, but here we go (I'm just quoting what I wrote in the other
group):

Unfortunately, the exact schematic does not appear online and is
copyrighted. However, it appeared in Radio Electronics Magazine
September 1986, p. 42 stun gun. A similar one adapted from the article
is here, but does not use the same components:

I built the gun from the kit in 1994, but my wife used it a month ago
and burned it out while scaring off a would be attacker.

I originally contacted the firm that made it, but have not heard back
after several weeks, so I went parts looking myself. I don't trust the
ones with the puny "400 KV" modules that seem to be front and center
now. This one really worked and was tested scientifically at the time
which is why I'd like to get the replacement components.
