SM-100
Commentary

High-grade stereo power amplifier with excellent frequency characteristics.

The SEPP-OTL system with series connected silicon power transistors is used for the circuit structure.
In addition, the damping factor can be adjusted in three stages.

It is equipped with an NF type filter that can cut the ultra low sound part.

The input level can be switched in 3 stages.

FET is used for the protection circuit, and it is a pure electronic type without mechanical parts.
