If the supply voltages are correct, measure every trace with an ohmmeter to make sure everything is conducting the way it should.

I should also probbably get a better soldering iron tip. Or a better soldering iron. (The crappy PCB does'nt much help, either.)

With the LM3875, P2P is a good choice. This site is shows a simple P2P build in small steps.

Good luck and don't give up.
After diagnosing the problem to be a fried capacitor, I simply removed the Zobel.
The amp works!
However, there's an odd problem: I think I'm only getting half of the signal (0 - +30 - 0 - (should be -30 ,but is 0) - +30, et cetera.) When I unplugged the amp and it was running off of the power filtering caps, the volume and sound quality doubled, and the nasty distortion disappeared.
I'll be replacing my rectifier, and if it works, I'm off to Olimex! Woohoo!
