Refer to the Accuphase C245 preamplifier circuit.
Use 2PCS BingZi 15W sealed Toroidal transformer for power supply. The left and right channels are powered separately, Improved sound separation and signal-to-noise ratio.
AA class operational amplifier servo power supply circuit is used. The unique design of this circuit enables it to provide optimal output characteristics, thereby presenting rich details and achieving low distortion signal amplification in audio signal amplification work.
Use Korean made SURGE audio filtering capacitor array.
Use Japanese ALPS potentiometer.
Use gold-plated RCA terminals.
Use the original imported silver contact fully sealed relay to switch inputs.
Use an all aluminum shell, it has efficient heat dissipation, beautiful and durable appearance.
