this is a HUGE help...
thanks so much. i've got several big 5v supplies lying around from various pieces of retired or broken gear. i'll open up my bcr and see if i can avoid blowing it up... :)

I measured the power supply connections on my BCR2000 a while ago:
1x 4.9V (red cable), 3x 5.4V, 3x gnd
I suspect a 5v, minimum 2A supply is all it needs. I wouldn't connect 12v past the power supply, it'll probably fry the components.
The supply itself is made up of the following components,
you can find datasheets online:
TNY268PN OFF LINE SWITCHER
4N35 OPTOCOUPLER, TRANSISTOR
YG802C04 SCHOTTKY BARRIER DIODE
