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.
Why not get the transformer rewound?
Do you have any suggestions on who to take it for rewinding?
Try Heyboer, they are one of the best.
Thank you Brf.
