RE: Power Supply Hum and Cabinet Cooling Questions

Paul's tips are graphically illustrated here, if you haven't already 
seen the Synth of Doom's power distribution scheme:

As far as closing up the back: you could cut vent slots at the top 
and bottom to help carry away any heat. Although the back of my cab 
is open, the power supply doesn't seem to generate any heat worth 
mentioning.

In the back, in the bottom, in the *center* of the cabinet. Then you 
make a wiring "tree" with 14ga wire. The tree goes "up" to each row. 
You use barrier strips/spade lugs to tie to each 'row'. Then, you 
place 2 MOTM-960s per row, to to the 'left' and one to the 'right' at 
the 1/3 and 2/3rds distance from the ends.
