DENON PMA-915
¥ 33,000 (around 1988)
Commentary
Thin pre-main amplifier with simple straight configuration.
50W + 50W (6 Ω) output is achieved by adopting a large capacity power transistor in the final stage.
A tone control circuit is used.
It has Route 6 (including Phono MM) audio inputs and two speaker outputs.
