MA-7
Commentary

This monaural power amplifier of the Music Link series was developed with a focus on the ability to reproduce music rather than on the mechanism.

The output stage employs a high-order strain-resistant power MOS FET in a parallel push-pull configuration, enabling a pure A-class 30W output.
In addition, the power supply section has been strengthened so that low-impedance speakers can be driven with sufficient margin.

Copper plated chassis and gold plated input / output terminals are used.
