[Boatanchors] FS: Elmenco Fused AC Plug

[Nick England]

Not to stir the pot too much - again....but the real issue is not polarized
vs non-polarized.
Install a grounded cord with a 3-prong plug and make sure there's a fuse in
the hot leg. A grounded chassis actually can save your butt.

FWIW historically, equipment designers took quite a different view. They
weren't totally crazy, and assumed users weren't either.
Standard practice in military gear is both sides of the mains switched and
both sides fused (and a grounded cord).
The T-R line between a Johnson Ranger and a Johnson Desk KW is a single
wire. The instructions say if the 115vac T-R relay connected between this
wire and chassis ground doesn't operate, simply reverse the AC line plug on
the Ranger so that wire is carrying the hot side rather than neutral..

And while we're on the topic, remember to always check the proper ground on
military line cords and connectors. For example, early CV-591 SSB
converters had hot AC on pin B of the chassis MS connector. Later CV-591A
(and most other military gear) have chassis ground on pin B. Plug an
old-style line cord into new-style equipment and don't get yourself between
the CV-591A chassis and the R-390A you're hooking it to!
