Luxman receiver info wanted

I just bought a Luxman R115 receiver from a local shop (a guy had traded it in on some tube gear). It cost $225 which was pretty good WAF, considering some of the ways I was THINKING about spending some money.

I think the sound is just awesome - it really pushes details to the front and pushes lots and lots of well-defined bass out there. It makes the modern Sherwood that it replaced sound like a clock radio. For my bedroom system it was a perfect solution (had considered a cheap tube integrated, but now have a tuner and phono stage to boot).

But I can't find ANYTHING on the internet about Luxman (except 4.78/5 AudioReview ratings for the 117&115 combined).

Does anyone know where I can find Luxman info on the net? I'd just like to know what their marketing schpiel was, and what their specs are/were.

Any info/links would be appreciated.
