Luxman L-308

Luxurious mid-to-high-end amplifier preceding the more remembered L-309, inaugurating LUX's staple Linear Equalizer circuit.

Linear Equalizer is a 5-step up or down "tilt" to the preset RIAA curve, rotating the 1kHz-centered frequency response up or down : more bass & less treble or more treble & less bass.
There is too much compression and standardization today to justify a Linear Equalizer, but given the highly variable response curve of the recordings back then, this surely was uselful !

The regular tone controls are Lux's (other) staple NF controls with selectable center frequency.

The circuit is a fully-complementary DC power amp section with dual-rail power-supply and 3-stage DC EQ circuit for the phono - Single-Stage, Duo-ßeta, plus-X and Circuit /S were for later years.

Compared to the later L-309, the L-308 doesn't have the back pot to attenuate the MAIN in input level, nor the MIC inputs with pulll-on/off level pot, replaced by tape 1 i/o jacks.
Bar power output, the rest is the same : 2-position low cut, 2-position high cut, low boost, stereo/L/R/Mono (L+R)/Reverse, 3-position phono 1 impedance selector, tuner input level pot and 2-way dubbing/monitoring.

Replaced in late 1975 by... nothing : the L-309 took over for that segment of the Luxman marketing and its many (many) (many) (many) (confusing) (diverging) (overlapping) (market-dependent) segments.

Beautiful, simple, healthy, shiny 1970s nevertheless.

A real 308 here.
