Commentary
An MC equalizer amplifier using Yamaha's original pure current amplifier circuit.
By constructing a pure current amplifier circuit with a satellite amplifier of FET configuration equipped on the head shell and main unit amplifier, the influence of lead wires and pin cords in the tone arm is eliminated, and transmission loss and pollution of weak signals are minimized.
It has an equalizer amplifier with level control and can be connected directly to a power amplifier.
Three satellite amplifiers are included : one with a high-end shell and two for your own shell.
