> the manual states that it can take from 12v to 18v DC safely, so it
looks like i'll be fine powering it off my 15v supply via the four power
connections at the back of the board.

Beware that the 4051 CMOS ic is being run from across the dual rails.
This means that you would have in theory 36V volts across a device that
is rated at 18V max. You may want to, as I did, take the -ve supply
pins, pins 7 and 8, of the 4051 to ground and not the -ve supply.
