Luxman R-820

Luxman R-800

1 9 7 4 1974
1 9 7 5 1975

Healthy AM/FM/MW/LW receiver with a 4-gang front end, symmetrical p-p and OCL output, NF tone controls, three pairs of speaker terminals, a beefy transformer with two primaries and no less than six fuses inside !

Very good-looking and seemingly available under the R-800 moniker as well but with no differences other than said moniker and substraction of the MW and LW receiving wavelengths.
The R-820 may have also seen a BIC /Venturi version as Luxman was then building for BIC...

Just like Sony, Luxman never did make many receivers : Japan, by and large, is the country of separates.

An optional 4-channel adaptor was available to give the classy walnut enclosure some of the hip 1974 frills.
