[R-390] Power Cable Hack

[Don Reaves]

Good Morning all.

I use $2 computer pigtail extensions - female to male IEC cables, short as I
can get 'em to attach to the back of my receivers. These pigtails are
usually 1, 4.5 or 6 ft in length and were designed for computer and monitor
power cable extensions(IEC-320-C14 to IEC-320-C13). I cut the cable and use
about 6 inches of cable on the male end wired directly to the terminal strip
of the R-390A, or to the appropriate screw on connector for the
R-390/391/389.  This works for other older gear too, especially military
gear.

This allows quick power line disconnects for moving or maintenance, I don't
have to deal with dangling power cables or unscrewing clumsy connectors, and
I can use a standard, ubiquitous business machine power cable of appropriate
length to suit my rack, cabinet, or desktop. 

No hacksaw, drills, or nibblers required.

Here's one prepared for my R-389:

Here is one extension cable source:

There must be thousands of places to buy these.
