I happened across a pair of rec/pb boards for a Scully 280B—they're untested and I'd like to make sure they're functioning or at least salvagable before deciding what to do with them. Problem is, the only schematic I have isn't very clear (attached) and some of the details are obscured, especially in relation to the edge connector labels on the left. I'm trying to work out what kind of power supply I'll need to test it, I can see +25v and -25v rails in places. Would a regulated, symmetric 24v supply work here? If so, is there anything recommended, and affordable?

Would I be right in thinking that one of these would be adequate for +/-25V? With a 24-0-24 transformer?
