Joe,

Open it up and look to see what connects to the screw-terminals. You can
trace the wiring back from the terminals and see where they come from -
obviously, that will tell you what's on the screw terminals (voltages,
inputs, outputs, etc., etc.). Even without a schematic you should be able
to trace the thing without any difficulty. Should be a rather straight
forward deductive inspection - unless I missed something in what you were
trying to say. I would think all you'd have to do is power the thing up and
measure to see what's at the terminals, if nothing else.

To the Boatanchor Crew:

I have just become the proud owner of a Kepco power supply that I want to
use as a bench supply for my BA gear. It has vacuum tube voltage
regulators
(7581s).

The Model Number is HB4AM. There is a 14 terminal block on the rear of the
unit with many screws missing . Something was once connected here, but
what
I can't tell. I don't have any information on what terminals should be
jumpered together, just the output and the 117vac line input. I know there
are internal links to the regulator, sense circuits, etc. I have tried the
Kepco website, which is unusually good and has never failed me in the
past,
but they don't have any info on this model.

I would love to at least get a connection diagram and ideally an operating
manual. I'm glad to pay copying and shipping costs. If any of you have
such
a beast in your possession, I'd surely appreciate the info.

Thanks and 73,

Joe
