C3850 Fully Balanced Class A Preamplifier Reference Accuphase C-3850 Circuit

Description: Introduction: The product has the functions of balanced input-balanced output, balanced input-single-ended output, and single-ended input-balanced output. It also has 2 RCA input options. Really balanced amplifier circuit, the power supply of left and right channels is completely independent, and the degree of separation is very good. The circuit reference is from Accuphase C-3850 preamplifier. This circuit is a preamplifier that is worth making and admiring. If you do it with your heart, the effect is much better than most preamplifiers. The sound field is looser, more delicate and warmer. Fascinating, because it is classic, it is far from the comparison between ordinary electronic tubes and independent op amp preamplifiers, and the sound can be compared with the timbre of electronic tubes. The circuit architecture is NE5534 Opamp as the basic amplifier. Discrete parts are added to increase the open-loop gain. The voltage and current dual feedback circuit is used to reduce distortion. The output tube uses the original UK tube ZTX450 ZTX550. The output is in Class A status. The music tastes very good. Input voltage: AC 110V or 220V (You can switch through the back switch.) Input impedance: 50K Color: Black or Silver (Optional) Output impedance: 600Ω Frequency range: 20Hz～50KHz Distortion: 0.003%@1KHz Signal to noise ratio: 116dB@1KHz Weight: About 4 KG Size: 372mm*52mm*241mm Package includes: C3850 Class A preamplifier X1 NOTE: We do not provide any cables.
