[HELP] Power and Stereo... oh my.

Hi All and thank in advance.

So in the last week I have been putting this together: http://imgur.com/a/rTLJ1

I just got the Lester K and decided to run it stereo between my HRD and my 67 princeton reverb... and holy crap. I have never played in stereo before, and now I don't know if I can go back.

The problem is this: the end of my chain goes Lester K (Stereo) --> Alter Ego x4 (Stereo) --> Carbon Copy (Not Stereo).

I love the carbon copy, is it worth it to replace it just to end the rig in stereo, and are there any small form factor delays that are stereo?

Also, because I feel like the board warrants something better than a one-spot... can anyone recommend a power supply that will power all of that?

Thanks all,

Andy <3
