Default 9v AC power supply for DAC

I have a small DAC board which requires 2x 9V AC.
Ie. the board has terminals marked: [9V - 0V], [9V - 0V]

Rather than having to drill and punch holes in a chassis for an IEC style socket, is it possible to use this plugpack:
Altronics - M9231 Powertran Appliance Plugpack 9V AC 0.67A

And then simply have a 2.1mm socket on the chassis?
Presumably I could take two wires from the centre tip to the 9V terminals, and then two wires from the sleeve to the 0v terminals.

Would this work, or will I require two plugpacks?

FYI - current drawn by the DAC is 60mA.

It almost certainly will not work. If you need 2x 9V AC then you need 2x 9V AC, not 1x 9V AC connected twice.
