Nakamichi PA-7AII , for owners or anyone who knows

I recently got this amp in December and was wondering if anyone knows any information on this amp. I want to use it in my stereo system with my Klipsch KLF30's. Any information on this will help out. Also can anyone tell me the WEIGHT on this BEAST!!??!!

Thanks Michael

The weight is about 62lbs. Power is 225 watts into 8ohms and about 325 into 4ohms. Please let me know if there's anything else you need to know.
