yes, but full nevertheless.
(3 for FM, 2 for AM), high Q tuning coil and low-noise FET tuner
equivalent to a full 4-gang varicap.
The european version has an "anti-birdie" filter added.
Duo-ßeta circuit, monolithic
IC for the EQ
section for high voltage and low noise, differential amps at input
and push-pull config at the output plus careful wiring pattern arrangements
for said EQ section, DC output with
large high fT and low
Cob transistors, flat and tone control amps replaced by a
tone control placed in the NFb circuit of the power amplifier to
improve open-loop characteristics, variable loudness control and
only 0,5mV residual noise.
38W per channel, though, but even if low-budget, classy Luxman nevertheless
and lightyears away from the 1970s R-820
or in-betweens like the R-1050.
