Do you have parts for an 845 Caztech amp?

I have a set of 845 mono block Caztech amps that are at least 20 years old. The company was in Canada and is no longer in business. One amp blows its 3 amp fuse and I have determined the power amp is shorted. There may be other issue that caused this power amp issue as well. I am wondering if anyone has a Caztech amp that is being parted out. I need to start with a transformer replacement and then go from there with possibly additional parts. Thank you.
