Lloyds was a 70s midfi staple - mainly all-in-one compact units, that sort of thing.
From the looks of the one you bought, I'd have to guess that it was one of their better units...but probably still only 5-10w per channel.
Sorry that I can't help further, but if it twists your knobs, then its worth what you paid for it. I, and I suspect many around here, find that the hobby sometimes is as much about recapturing a memory or satisfying a long-ago lust (even one that has been outgrown or superseeded) as it is about absolute fidelity. That's one of the reasons I have tossed a few bucks at things like a Panasonic RA6600 8-track recorder/receiver and a GE R-504 receiver, as well as at the 'better-fi' stuff. For the price of a fast food lunch, why not?
Keep it fun!
