Hi Fred,

The SP3 has a lot of room inside and is very solidly constructed, so it's a great platform for a DIY add-in like a power supply. You would only have to modify one piece of sheet metal -- the bottom cover -- since that is also the mounting point for the A/B switch in front and jacks in back. 

Available interior space is approximately 3.3"H x 5.9"W x 7.3"D. Audio jacks are arranged vertically along one edge of the rear panel, leaving several inches of space for additional connectors, possibly even a small fan.

Of course you'd have to remove some of the acoustic baffle material, altering the AF response curve in an unpredictable manner. Just thinking out loud, here, but I wouldn't use it as a hiding place for your collection of rare idiophones. 

73,
