Very nice amp. Very clear sound, but little headroom. Also, runs very very hot. I had a different model, but you could fry an egg on the top of it. This amount of heat has adverse effects on the parts inside, especially after a number of years in use. It may need quite an overhaul to really get the best out of it again. It would make a fun project to replace all the caps, resistors and wiring with the latest types to see how it may improve. Just my thoughts. Good luck.
