Luxman L-4

October   1 9 7 8 october 1978

A 1980s update to 1970 looks - that "L" series was inherited from the magnificent but very rare SQ202 - would've been better in a wood enclosure but to my knowledge that option wasn't offered.

A fair amplifier with PNP/NPN-loaded phono and output stages, the L-4 had its input plugs placed on its underside, as close as possible to the volume board to avoid long lengths of cables back and forth.
The same idea was offered at the same time by Yamaha (A-9), Sony (TA-F80) and others of course. Putting them on the top (Yamaha) or to the side (Sony) would've been easier for the end user I believe ;-)

The L-4 was from the "Studio Standard Series" in some countries but it also was from something else in Japan and again something else... elsewhere.
And given Luxman's complex distribution schemes and versions, the L-4 probably also was available as something else -if barely different- here, there and everywhere, for longer... or not.

You can see a real L-4 here.
