SONY TA-3140F

Commentary

This is a stereo power amplifier developed to cope with upgrading of the amplifier section and multi-multiplication.

Carefully selected pairs of transistors and specially developed multi-supply power transformer with good regulation are used.

The frequency characteristics are improved by using a transistor with a high cutoff frequency and setting an appropriate NFB circuit constant.

Equipped with level control.
