McIntosh P965A Programable power supply

[waterbug]

I am new to this forum and already appreciate any help you can offer. I have been out of work on dissability and am experimenting with electronics (not since Vietnam have i been doing any electronics and I'm pretty bad at it now). I just purchased a used power supply and before doing too much, I would like to see what a where the power comes and goes. It's rated output is 0-13.5 VDC and 0-6AMPS. good for the auto EFIE and PMW I am currently working with. The unit is originaly designed to plug in to a board of some kind that has the output and contol ckt.
Thanks for being here..
