SA-31

Hybrid Stereo Pre-Amplifier

A combination of valve sound and high transistor performance. The SA-31 preamplifier works with highly precise ALPS potentiometers. The amplifier connections for the right and left channels are separate in order to achieve a low noise voltage distance. The output amplifier is designed with Class A technology. Inputs and outputs are optimised.
