Looking for a Dayton SPA-250 schematic

Not sure if this the right place but here goes... I have had four Dayton SPA250 Plate amplifiers over the years and they all fail after a while, usually five years down the road. They just blow the fuse and go dead.


I was wondering if anyone knows where I can find a schematic for the amp to see if i can get any of them fixed. I contacted Dayton and they would not provide me with one.


I guess I shouldn't complain too much as these amps seem to last for a while. My two SPA500s and SPA1000 are running about 10 years old and still going strong. My Polk subwoofer and Velodyne amplifiers had failed at only a couple of years.


Thanks in advance...

I wonder how the Chinese can time the failures to near perfection ?


Yes they have factories in "Asia "
