SU-7600 :

Stereo pre-main amplifier with fully discrete power amplifier.

The power amplifier is a discrete type using low-noise and low-noise transistors.
The OCL circuit consists of an all-stage direct-coupled differential-amplified complete complimentary service OCL circuit. An emitter-follower is inserted at the latter stage of the differential amplification to improve matching with the latter stage and to reduce distortion at the time of small signals.

A specially selected IC is used for the equalizer circuit to achieve low noise and high stability.
The circuit configuration is 3-stage direct connection system.

The tone control method has succeeded in reducing frequency fluctuations and increasing the range of tonal changes.

It is equipped with double protection circuit of relay and fuse, and it prevents transistor and speaker from being damaged in the case of emergency.
The relay circuit also has a time constant to prevent shock sound when the power is turned on.

Two tape decks can be connected, and dubbing from 1 to 2 is possible by operating the knob. Two speakers can be connected.

It is equipped with a loudness switch which is effective for low volume and a high filter which removes high-sound noise such as scratch noise.
