SONY TA-3130F

Commentary

This is a stereo power amplifier developed as an optimum amplifier for multi-channel applications.

A differential amplifier circuit is used in the first stage of the amplifier to stabilize the operating point.
It also has a built-in protection circuit to cut off any abnormal voltage generated on the output side and protect the speakers.

Equipped with input level control.
