[Elecraft] Why Black

[Fred Jensen]

It's for heat radiation.  Basic thermodynamics ... black body 
radiation.  Just took awhile to figure it out. [:=)  I've wondered when 
the black crackle finish fell out of fashion.

So if you got two cabinets painted in different lots, odds are the greens weren’t quite the same.  I think WRL “gray” was also a variety of shades, some tending towards greenish.  It wouldn’t necessarily be obvious in a standalone situation, but when you lined up the cabinets the color differences could really stick out.  I remember that my 1970’s SB-640 external VFO was way off from the SB-102 I’d built a couple of years earlier — both front panel color and cabinet color.
