A costly mistake and live and learn (they say, but who actually does that...?), however it was limited to just one amp board. Still, I had to tear it all apart and check everything to make sure there wasn't any collateral damage. That's the BIG downside of putting so much in one case - it literally took a full day to do that.
With the blown board swapped for one of the "spare" channels, I got it up and running again. I'll eventually repair the amp board that blew and reinstall it, but like I said I don't really need it right now for anything important.
The two new crossover boards are for the infinite baffle subwoofers that are in the front wall of my listening room. They are powered by a separate 4 channel amp that I built nearly two years ago and featured that build on this channel. While it isn't quite finished, it's finished enough to use every day until I find time to complete it.
The crossover points for the sub boards are 15Hz high pass and 80Hz low pass. Both slopes are 4th order. I need to make another for the bass shaker I have in my chair, and that will use the 9th amp board in the case.
I need to put the brakes on this new multichannel amp (name change, in case I blow any more boards...) for now, so I can get back to my real occupation - making woodworking videos on YouTube. I'll get the rest of it done when I get the time.
