PET power supply questions

Hi, all, I've been collecting various classic bits to work on over the winter, including a pre-CTRC 32K PET board (2001-N/3032) and a Static PET board. I don't have any cases or accessories, but I do have a C2N232, a single bare keyboard, and a C=Key converter enroute. For video, I was planning on trying that ancient XOR circuit to make composite video Obviously, I'm unlikely to find a suitable mains transformer, so I was going to cobble up some form of switcher that puts out enough of the right voltages to make this all work. Poring over the schematics for the 2001-N board on zimmers.net (e.g. 320349-9.gif), I'm guessing that the onboard regulator circuit is pumping out +5VDC at over 5A, +12VDC at a couple of amps, and a miniscule amount of -5VDC. I'm not running a real tape drive, so I'm not as worried about the +9VDC unreg. Does anyone have any reasonable estimates or real-world measurements for the current draw on the various supply lines? Has anyone out there ever gotten a PET to run from externally regulated DC?
