I just found out that the lower part of the cable is an adapter. It seems, then, that two of the wires were switched. Mystery solved. Thanks again Sachu.
This is a weird one. Maybe. I fired up the amp with the top off, turned on some tunes, and everthing was sounding great. Then I reached my left hand in to touch
the PS heat sinks and zappo! Turns out that the exposed metal can portion of the negative rail filter cap is at -315V. Would that indicate that the cap is
somehow shorted internally. I removed it, and all seems normal. Any thoughts?
BTW, no problem with the positive rail cap.

Not sure what dude_500 is saying, because the can of the cap is connected directly to the negative terminal. On a single rail power supply this naturally sits at ground and there is no problem. On a dual rail power supply it sits at the negative voltage below ground, which is a problem.
Life lessons well learned, eh?
so the hot cap kinda' surprised me.
