Ok, mixed review here:
1) Love the head, sounded excellent in the first gig with an acoustic 115 cab I’d brought there. Actually vibrated crazy in the church, such I haven’t heard… A+ all around! In the second gig I was able to use the boogie channel more, which seemed to fit the songs better. More of an old school R&B kind of gig. Really hit for slap on the subway channel, too…
2) Bad news on the 3rd gig - I might’ve burned the 115 speaker… I had used the tt800 with a combination of the 115 and a 4ohm Ampeg 410 which came out to 2ohm and seemed to be sounding huge and really deep. Loved it, but after a couple of songs I got nervous because I heard some overdriven sounds and thought it was the 410 getting too much power. I reduced down to just the 115 and after a couple very driven slap songs I heard a lot of distortion, it seemed quieter, and smelled a burning smell. I smelled this same smell at another gig as well, couldn’t tell you when, but now it was certain… I just tried to work with it. It seemed okay-ish once I turned down for preacher talking stuff and alter call. Got through the gig.
After everyone left I tried to get my ear around what was distorting, and it was definitely the 115 cab. My other Ampeg was a lot louder and clear with the tt800 (though I could probably benefit from new tubes) but both the minimax and the mesa are distorting through the 115… I’m afraid I broke the cab by having the low end all extended and boosted, and pushing the speaker for too long and too hard. I am bummed, but at least I have other cabs.
Thinking I should just trade up for a 215 or a 212? I was pretty sure I was within the 400 watt realm at 8 ohms, I wasn’t more than half up on the master and at the low gain setting. I did have the MM5 dimed out on the bass and master, and the deep switch engaged on the amp. I left the hpf all the way down too, didn’t think it would hurt anything but I guess I’m a dummy.
Still, loved the tone I was getting until it lost volume and got all distorted.

It’s just a really loud environment, and it gets really rocking and driven regularly. Pentecostal, modern gospel and R&B… lots of low B string stuff and slap.
Should I get a 212 or a 215? Will that be safer and still get me in the ballpark? It is under warranty, so I’ll be able to get a speaker swap if that’s the best thing…
Help? Any direction here?
