Sean,
The company itself has been around in some form for several decades so I'm not so sure that there are that many completely "original" employees :^) but I imagine that it's much like other smaller Japanese audio companies - the employees/facilities/philosophy stay the same but the boss changes - something which has happened to a horde of them: Kenwood, Nakamichi, Denon, Marantz, FR, Akai, SAEC, MicroSeiki, and others... Still others had their hey-day and then moved down-market or reduced operations.
I am curious though so will see what I can find out by calling the company. If anything, I'd almost see the possibility they could eventually be bought out by D&M Holdings, the firm which was established after the merger of Marantz and Denon not long after Ripplewood effectively took over management control of Nippon Columbia (which owned Denon before that). Luxman sales are so low globally that it might make sense.
Dazedandconfused, I think sogood51 is probably right on the specs. I cannot find the L-2 in the product history of Luxman on their Japanese site but the L-1 and L-3 are both listed as having been 35Wx2. The time is about right too as the L-1 went on sale in August 1980.
Hope you enjoy it.
