- While I'd rather not receive any electric shock at all, I'd rather get
- bit by the flyback (high voltage, but a fairly "dry" circuit) than the
- B+ supply (enough voltage and hundreds of mA at the ready) any day.
- KISSING it doesn't seem like such a good idea, though.
-
- If you're grounded properly you can get yourself a good smack with
- 110V ac as well. People tend to dismiss it because most of their
- familiar shocks come when they're poorly grounded.
-
- Got to admit, this CAN be funny in a macabre sort of way. We were
- rolling on the floor in high school physics when one of our putatively
- brainier classmates pointed out some feature of his tesla coil with
- a pencil while his other arm brushed against the lab sink. Figured
- the wooden pencil would be a good insulator. Forgot about the graphite.
- Of course, if he'd ended up with cardiac arrest instead of near-lethal
- humiliation, it wouldn't have been quite as funny.

-
- If you've never put B+ across the filaments, you haven't worked with
- tubes very long. Gotta admit, though ( * snicker * ) that most people
- learn that lesson when smoke-testing a new or repaired chassis, not
- with the ol' "digital voltmeter"...
-
- Not long ago, one of the ham radio rags saw fit to remind their readers
- that tube-type equipment generally does not run on +- 12V and +5V. I'm
- too young to feel that old. Followup to alt.electronics.geritol?
