Commentary
Integrated amplifier with vacuum tube and MOS FET for high-quality music reproduction.
A high-impedance FET is used for the first stage, a 3-pole vacuum tube is used for the driver stage, and a MOS FET is used for the power stage that handles large electric power.
Vacuum tube It brings out the rich nuances that are unique to the product and has acquired extremely high quality musical expressions.
Equipped with Route 3 video input and monitor jacks, it is possible to dub from AV2 to AV1.
When dubbing, a wide-band video buffer amplifier is used to prevent image degradation.
It uses a STAR circuit with separate power supply lines and ground lines for each circuit block and amplification stage. Moreover, by eliminating common impedance in signal lines, mutual interference between circuits is avoided, enabling high-purity music playback.
It is equipped with 230 VA large super regulation transformer.
Equipped with a constant current heater circuit that prevents AC power supply fluctuations from reaching the heater.
It is equipped with CD straight function so that you can enjoy fresh CD playback.
