Luxman L-31
c.1976
1977
The L-31 is the more powerful and slightly later sibling of the L-30 ; team-wise, it also fits the T-33 tuner.
Hardware- and circuit-wise entirely identical :
dual-rail differential driver power supply, low-noise preamp, 2-stage DC with PNP/NPN phono stage, an impressive damping factor and cutie styling alternating aluminium and plastic knobs on a very elegant aluminium front surrounded by a luxurious rosewood enclosure.
The scripting is however very lightly silkscreened - beware when cleaning it up.
Nudies aplenty here.
