I imagine the 900-PCB is a PCB with a
bunch of headers on it. So I'm thinking
(I know, bad idea!! :) that I can mount the
900-PCB on the wood behind one of the
modules

Mark, I have three of the PCBs in my metal rack. The existing ones have 12
MTAs and also some push-on faston lug connections that are designed to be
the source. You don't want to feed the PCB distribution board with # 18
wire. You want to use something larger if possible between the PCB and
power supply. I use # 14 stranded in all mine.

Personally, I don't see that mounting the PCB wood is a big deal. At 15
volts, wood is a pretty good insulator. At 15,000 it woudl be a bad idea.
However, when I mounted mine in my metal rack, I just went to Radio shack
and bough some of those shallow $3 project boxes with the screw-on lids,
just big enough to hold the PCBs. I tossed the lod and mounted the PCBs in
these plastic boxes. Worked out real nice.

and then build a cable with a MAT-1564
(AMP#640426-4, right??) on one end and whatever
on the other.

Personally, I would not use the MAT-156 connector as the source to the PCB.
The PCBs are set up for a better source connection. I can send you a photo
of one if you like.

I've been looking through the Digikey catalog for various options.
Switchcraft makes XLR's with more than 3 conductors, but they get a bit
pricey. Considering that I don't need metal because there is no shield,
I'm wondering if there is something like a plastic Molex or Cinch-Jones
(like on a Mini-Moog) connector that is both chassis mountable and round.
Cutting small square holes or anything but a circle is difficult with the
tools I have, and I do not want to invest in a panel punch.

Amphenol makes some real nice round connectors too. However, they are
pricey also. I would not consider Cinch-Jones for a power connector. I
would prefer something that is locking. The last thing you want is your
power supply cable popping out on you.
