MOTM

I've seen some CP131A's on evilbay 'new-in-box' for cheap.  Worth it?  Hmmm...
Need to beware of date codes since those $$$ Mallorys might need replaced
(especially if 'new-in-box').  In my opinion, too much 5V and not enough 15V,
even if it works.  (Boy, wouldn't it be bliss to have enough 500/600 modules
for 8A of current draw!?!)

I've gone two separate supplies route:
HCC15-3-A: +-15V@3A (got off evilbay for $25)
HC5-6/OVP-A: +5V@6A (still looking..)

Anyone find any deals on the HC5-6/OVP-A ?
