[sdiy] External power connectors

[Harry Bissell Jr]

LOL.  I use SEVEN PIN XLRs for my hex guitar synth
cable. You DO NOT want to know what they cost.  I used
six pins (with the shell for ground) but it was not a
good contact.

For my synth cabinets I use DB-25 computer cables for
power and CV distribution.  Parallel a few pins for
power and you would be fine, and redundant as well.

They are dirt cheap and available everywhere. Inside
the synth cases I made a PCB to hold the connector and
fan out the cables, so it forms the power distribution
block as well.

So its not MOTM / Blacet compatible. Sue me :^P

H^) harry (well I lied... at the OTHER end of the
internal cables I am MOTM compliant :^)
