[sdiy] DC plugs and outlets

[David G. Dixon]

OK, now that my gate clicks are sorted, here's a new question:

I need to build a second cabinet for my growing collection of orphaned
modules, and need to transfer DC power (+15/0/-15) to the new cabinet.  What
do we use for DC outlets and plugs?  Is there a standard thing?  Mouser/
Digikey/ Jameco/ SmallBear catalog numbers are fine.

Also, does anybody have any quick keyboard housing plans on the web?
Woodworking is not my strong suit, but I was able to cobble together a
decent cabinet from the plans on www.synthesizers.com.  I'm wondering if
there is something similar out there for keyboard housings.
