[sdiy] Dotcom synth supply rails harness suggestions needed...

[Jean-Pierre Desrochers]

Nice board !
What wire gauge did you use to wire the 'main'
4 pins lower connector to the actual supply VCC lines ?

One way I could also do is use your PCB approach
but instead of get it made 'square' with 3 connectors rows
I could have 2 long PCB's with VERY fat paralell VCC, GND traces,
and both PCB's placed in series, aligned in a row screwed on top of my inside cabinet.
close to all the MTA156 connectors.
Each PCB would have 11 connectors aligned
with modules connectors. Links to each modules could be
done with lighter gauge like #22-24.
The edge of the closer PCB from the supply
would have terminal block that could accept gauge#10 wires
for 'no voltage drops' to the main supply VCC connectors.
The FAT traces on these PCB's would have the same behaviour as
a 'star' mounted wiring to the main supply but with less wires
all around the sides.
What do you think ?
