NIKKO R-2000
¥ 33,900 (around the early 1970 s?)
Commentary
A stereo receiver designed to hold a large record player directly on top.
It has a depth of 38 cm and can be used with a large player on top, saving space.
The circuit consists of TRM 300 and FAM 300 packed in as it is, and uses a design using IC, FET and ceramic filter.
The preamp section and main amplifier section can be separated by a switch, making it possible to use 4-channel or multi-amplifier.
Equipped with two speaker outputs.
The FM tuner section is equipped with an automatic multi-circuit that automatically switches between stereo and monaural.
NIKKO circuit breakers are installed on the primary side (input side) and the secondary side (output side) to protect from electrical troubles.
