Tube Crossover Board Mounting - PS section front or back?

I'm getting ready to wire up one of the new VTA Tube Crossovers. I have the standard chassis for it, got the panels drilled & milled to my liking.

As I'm ready to load up the transformer and circuit board, I'm in a bit of a pickle.

Do I want the power supply section closer to the I/O in the back or the pots in the front?

I'd appreciate comments so here are some pictures of the layout.

Cheers,

PS. Roy made me a deal I could not refuse on hie prototype board / kit. Ready to go!

this question was answered directly via email - the answer is to keep power transformers away from the inputs
