Luxman LV-111 (1979–1981)
The Luxman LV-111 is an integrated amplifier from the turn of the 1980s, produced between 1979 and 1981. It was a straightforward, high-powered Class AB design rated at 100W per channel into 8 ohms at 1kHz with 0.02% total harmonic distortion. Input sensitivity was 150mV, and the damping factor was rated at 100.
It was a substantial piece of equipment for its era, measuring 440 x 156 x 386mm and weighing 15.2kg. Past the core specifications, the documentation is thin. No detailed design notes, circuit topology or historical context have survived in the usual sources. What the record shows is a competent, powerful integrated amp from a period when Luxman was producing a wide range of separates and receivers. The LV-111 appears to have been positioned as a straightforward high-current workhorse rather than a flagship.
The LV-111 doesn't appear in the period reviews that have been preserved for other Luxman models of the same era. Audio (1990, p.332) covered integrated amplifiers extensively in its annual equipment surveys, but the LV-111 is absent from those listings. It had likely been discontinued for a decade by then. The amplifier seems to have been sold mostly in the late 1970s and early 1980s, without the press attention that some of Luxman's more exotic hybrid designs received.
Known specifications:
- Output: 100W + 100W (8Ω, 1kHz, 0.02%)
- Amplifier class: AB
- Total harmonic distortion: 0.02%
- Input sensitivity: 150mV
- Damping factor: 100
- Dimensions: 440 x 156 x 386mm
- Weight: 15.2kg
The LV-111 turns up occasionally on second-hand markets, though current pricing data and common failure points are not well documented. For a Luxman integrated of this vintage, the usual checks apply. Check the condition of the volume potentiometer, look for signs of capacitor aging, and verify that both channels output cleanly before purchase.
