Sorry. I guess I should have said. I didn't mention it as I felt kind of silly not knowing, but I suppose if I didn't know, I'm probably not alone.

If you're going to get behind the amp and start rearranging/disconnecting things, wait for a couple minutes after unplugging it. The capacitors take a while to dissipate their energy and you could easily discharge that energy in an unintentional manner if you don't wait. It probably mentions that in the manual somewhere as well (even though I didn't notice it), but I sure appreciated having it pointed out to me.
