SONY TA-3060

Commentary

This stereo power amplifier was developed as a simple amplifier for multi-channel systems.

It is designed to minimize cross modulation distortion as much as possible, and not only circuit technology but also transistors and other parts are carefully selected and used.
As a result, even if the best measuring instrument available at that time is used, it is impossible to measure due to the distortion of the measuring instrument itself.

All stages of the power amplifier are directly connected and the coupling capacitor is eliminated to eliminate adverse effects.
In addition, because of the direct coupling method, sufficient power can be obtained even in the ultra-low range, a built-in filter for speaker protection is incorporated.
