[R-390] Power Cords and Bypassing: Roy's Diatribe

[W. Li]

Nice essay, Roy! One can not ever be too careful in
power input circuitry. 

Here my note from 1999: "Not all FL101's are the same.
One of mine has the terminals mislabeled. Terminal A
on the side of the power filter was in continuity with
terminal "B" on the bottom, and vice versa. My other
filter was labeled correctly. So a word to the wise:
do a quick continuity check on the power
cord-fuse-switch wires when you install the mandatory
three wire grounded line cords".

Perhaps the "best" solution is to install the modern
AC  computer-type chassis connector with filtering as
Roy suggests.

A good article on restoration our boatanchors is found
at QST August 1995 pp49-52 by Larry Keith KQ4BY
