Trying to find replacement for built in amp

[stlb5]

I've got an older Klipsch SW-12II and the amp is fried. Where can I find a replacement amp? I looked on Parts Express, but none of their amps would fit. The built in amp is about 14" by 6". I only need about 150 watts.

Did you check with Klipsch?

yes, still waiting to hear back. I just don't even know where to look for these otherwise. When I search the internet, most of what I get back are car audio sites.
