Yeah, I'll look for a 16v power brick. Still, I'm worried, as that supply was emitting more than 500mv of ripple! Seriously, I could just watch the needle wiggle on my multimeter. From now on, I'll test my older power supplies before using, and I suggest others do the same. If it's not fairly stable when it's not even at load, it needs replacement.

No wonder why the darned thing was crashing!
