[AMRadio] [AM Radio] A special day today

Had a Knight T-60 transmitter as a Novice. I had tapped the power supply for
some reason through the rear plug. When whatever that project was over,
rather than remove the wire, I cut them off.
Went to change coax and, as I leaned over and reached behind, I accidentally
keyed the transmitter as my wrist was across those @#$%^&* wires. I flew
across the shack on my swivel chair and hit the filing cabinets hard enough
to cause the drawers to open. My head and my wrist were quite sore for a few
days. I started removing wires like that immediately.

According to Wiki, the holiday did not start till 1986.

But an interesting story non the less.

I was first bit in a electronics shop class. I was checking out a
power supply I had built for a small 6L6 transmitter. Got bit by a
lytic when it was off. (oops did I forget a bleeder resister) I
cleverly reached in and got it again, thinking my first go around had
discharged the cap.

My classmates found it amusing.
