Can an owner's manual and schematic be found for an Electron Kinetics eagle 7a power amp

Hi Guy’s, out there in Audiogon world! I just picked up an eagle 7a power amp, the guy that I got the amp from said it had been in storage for years and it was still in the shipping crate but no owner’s manual or schematic. can anybody tell me if this is a good amp or a waste of money for $300.00, I don’t know much about this power amp, but I would like to power a pair of Acoustats 6+6 I am willing to purchase a manual and schematic from anyone on the forum if that is possible. The strange thing about this amp is it don’t have a power switch. and are there any techs that can work on this amp, what things should be updated on this amp since it has been sitting in a crate. I had the guy plug it up and it played fine, does the a after 7 mean anything on this amp on the model number? I would feel comfortable having looked over and not after it goes up in smoke. any help would be appreciated. Thanks, guys!
