Plate amps in commercial subs are often custom sized & labelled by OEM makers- i.e. not built in house - and are often purchased in a contracted bulk lot, and very hard to source late in, or after the end of warranty.
Have you tried contacting Klipsch directly?

A very annoying phenomenon that a buddy of mine who's been a car installer & speaker repair dude for over 30yrs relates is that not only the higher failure rate of plates amps in even prestige commercial brands than with the attendant drivers, but the unavailability of "correct" replacements - period.

Why there's no physical isolation between the amps and working volume of the sub- enclosures in all cases is beyond me.

If repair part is not available, you may may well be faced with finding a comparably powered BASH plate amp and perhaps modifying it or the enclosure's opening to fit.

german klipsch-dealer recommended to send him the amp-module for repair.
it will cost overall 150.

i think its cheaper to repair it by myself.

anyone has a schematic from the amp in the sub or maybe has a sw-115 at home
and can take a pic of the broken IC ?

You can only repair it yourself if the part is identifiable and available for out of warranty service - as I noted above, even with popular commercial name brands, neither is guaranteed.

and of course, there's no assurance that the obviously smoked parts are the extent of damage / failure

Hello,
Did you find a solution ? (schematic, new parts,...)
I ask the question because I have almost the same problem.
