Analogue systems

I did the same thing with my side cabinet (there's no pictures of that yet,
but it's three rows large by about 20 inches, rounded off to the nearlest
RU).  I used separate +/-15. +/12 and +5 supplies, all Condor, all very
protected as afar as short circuit foldback, and on the side inner wall of
the cabinet I hung a large vector board in which the traces consist of long
rows down each row of holes - perfect for making busses.  There are two rows
of A. Sys dip sockets (24 of them), two rows of doepfer (same number) and 1
row of .1 spaced modex four in line sockets for various 15 volts modules.  I
will never have room for that many modules n the box, but sockets are cheap
and this was an inexpensive and effective solution.

I also hung led's on this board, one for each power line hung at the end of
each buss and made a faceplate for an an/off switch, which has another set
of leds going directly to the PSUs.  This way if there's ever a power
problem I need to hunt down, I can isolate in a second where its coming
from.  If all the faceplate lights are kits, it's not the PSUs.  If one of
the bus board lights aren't lit however, then I know the problem is on that
board.
