Ok Rob, this looks pretty simple, and that's a pretty fine photo you took. I still can't quite follow the diode connections but it looks like they have them connected to produce a positive and negative on the input of the two linear regulators. I'm not quite sure why they have four diodes since this would be a half-wave rectifier circuit. Maybe two are connected as protection diodes? Are those pairs of electrolyic caps connected in parallel? Do you have a DMM/voltmeter?
