Commentary
This is a preamp of the Music Link series that was developed with a focus on the ability to reproduce music rather than on the mechanism.
A 14 dB gain line amplifier is used to drive the power amplifier with sufficient margin.
In addition, the input system is limited to four systems and one system for the tape deck, so that the configuration is simple.
Bi-amplifier drive or BTL drive of the power amplifier is possible by each output of positive phase and negative phase.
The output circuit is a unique output transformer system that employs a transformer coupled multi-feedback circuit.
Toroidal transformer and copper plated chassis are adopted.
