LUXMAN vintage audio
Luxman L5 Amplifier
Around 1980 Luxman company came with its L5 hi-quality amplfier on the world markets.
Luxman L5 Integrated amplifier effective output:
(both channels driven) minimum 60W+60W RMS (8 ohm, 20Hz - 20kHz)
THD: (20Hz - 20kHz) 0.02% or less (8 ohm, 60W)
IM distortion: (60Hz:7kHz=4:1) 0.02% or less (8 ohm, 60W)
Output bandwidth: 10Hz - 80kHz / -3dB
Frequency range Phono1,2 less than [ 20Hz-20kHz ± 0.5dB ]
Tuner, Aux, Monitor1, 100kHz [ 10Hz - ]-less than 1dB
Main in: 100kHz [ 10Hz - ]-less than 1dB
Tuner, Aux, Monitor1,2: 150mV/50kohm
Main in: 1.25V/50kohm
SN ratio (IHF-A correction):
Phono1,2: 80dB or more
Tuner, Aux, Monitor1,2: 100dB or more
Main in: 100dB
Damping factor: 70 (8-ohm, 1kHz)
low-pass : 200Hz, 400Hz
high-pass : 2kHz, 4kHz
Subsonic: 15Hz-6dB / oct
low cut: 70Hz-6dB / oct.
high cut: 7kHz-6dB / oct.
speaker protection by DC sensing
Overcurrent protection circuit
Audio Attenuator (-20dB)
Tape monitor &cross-tape dubbing
Rec out off-switch
Supply voltage AC-100V/220V, 50Hz/60Hz
Power consumption 170W
Dimensions Width 438x height 105x depth of 313mm
Special tape-dubbing, Tone is defeatable. Subsonic filter. Torodial mains transformer.
This amp is one of the better Luxman amps and has lots of power to supply your speakers.
On a updated L5, I measured 2x75 Watts RMS.

The L5 is powerfull and the sound is great.
Some L5 suffer bad variable resistors for setting DC offset and idling current.
Some caps can be not the best quality and can be replaced.
DC decoupling on the power amp board can possibly be improved.
