Luxman R-1050

1 9 7 7 1977

Luxurious looks and, as the immense majority of receivers made in Japan, export-only.

Hidden by said luxurious envelope are a 4-gang tuner with dual-gate Mos-Fets, PLL MPX, linear phase ceramic and block filters, DC-coupled amp with dual-rail power supply, output muting circuit, NF type tone controls, constant voltage supply, a few "eye-catching" LEDs, and... Dolby FM !
Ah, well, optional at any rate.

The smaller R-1040 did away with a little power, lesser tuning specifications, the center-tuning display, tape-dubbing facility and the Dolby FM option.

Very good looking in its genuine wood enclosure - Luxman elegance, even in mid-end audio toolboxes.

Replaced by the similar R-1120A which mainly swapped the roundy separate LEDs with rectangular bar-graphs of... LEDs.
