Commentary
A stereo power amplifier developed with the theme of bringing out the capabilities of a speaker system in pursuit of sound transparency.
The circuit configuration is 2-stage differential amplification, all stages are completely directly connected with two positive and negative power supplies, and OCl system is adopted.
It is equipped with temperature compensating transistor, differential amplifier stabilizing circuit, power transistor protection of quick disconnect fuse and speaker protection by SCR to improve safety and stability.
It is equipped with an emitter-follower input circuit, an input limiter circuit using a varistor, and separate left and right VU meters that can be switched to four stages.
Two input / output circuits are mounted on the left and right sides respectively, and separate phase switching switches and level adjusters are mounted on the left and right sides.
Equipped with a headphone jack.
