Help identifying burnt component klipsch sw450 subwoofer

[Marcpe]

Can anyone help me find the part value of this burnt component underneath the powerboard of klipsch subwoofer sw450. My best guessed is TNY278GN its a 7 pins chip.

That is a pretty good guess. Klipsch used one of those on their SW 115 too.

Great. Appreciate your quick feedback at least I have peace of mind when replacing it. My subwoofer fuse was blown when I tried to check the board I found this burnt U2.
Thanks again.

I'm just saying that is likely. It's not my amp so I can plant fictional seeds and see if they sprout.
