[GreenKeys] Loop supplies. Again.

[in my BEST Ah-nuld schwartzenegger voice]...

Yah, yah, only gurlie-men run low voltage/current to
their selectar magun-nets.

reee-yul men connect the plate cap of their linear
amplifier to the loop to make sure those magnets
open and close with power!

Aye-teenun volts iz for vimps!!!

Oh - and remember: if God didn't mean for you to type in
CAPS, He wouldn't have allowed the Teletype to come into existence...

Inventions reached their limit long ago,
and I see no hope for further development.
