Jimmy,
 
It's a Pyramid Model: PS-15KX. 
 
You guys (particularly Roland) have shamed me into figuring out what the problem is.  So in the interest of "science" and hopefully helping others, I'll contact Christopher off-group and ship the thing to him in Hawaii and see what he can find out.

I see you still have 13.8 volts between the positive and negative terminals.

Shorted cap, possibly
May be same cap your friend replaced.

Positive terminal shorted to -11 Volts below protective ground?

or

Negative terminal shorted to -25 Volts below protective ground?

I don't understand a solution to these results.

I do enjoy troubleshooting and brain teasers.

What model PS do you have and do you know of an on-line schematic.

If not, I don't think I can help any further.
