Powering Monica & I/V Gain Stage - Opinions Wanted

[Xyrax]

I recently ordered a Monica2 with the SS I/V Gain Stage. I am trying to decide how to power the thing. I had some ideas and would like some opinions on them.

1) (probably the easiest solution) Add 2 TREADS to the enclosure. One set to 12v for the Monica and the other to 15v for the gain stage. Both powered from a single wallwart by connecting them to it in parallel. Any problems with this set up? How much current will the wallwart need in order to power both TREADs?

2) (more difficult) I'm already building a STEPS (24v) and PPAv2. I could add a second output from the STEPS to power the DAC and gain stage but I would have to drop the voltage by half for the Monica and probably end up with a space heater in the process due the the regulator.

On a side note, does anyone know the dimensions of the Monica2 and the gain stage? I need to find an enclosure for everything.

TYI

The 1st option sounds good. I think ~500mA wallwart won't have problems powering the Monica + SS I/V.
