Product Details:
This is a globally renowned Dream Voice 300B single ended classic circuit, with a mature circuit section, simple design, and excellent performance Excellent sound effects.
1:) A 100K volume potentiometer is inserted between the voltage amplification stage and the driving stage, which can control the gain and also serve as a load for the voltage amplification stage, playing a dual role of voltage amplification and preamp
2:) The push stage is composed of a SEPP circuit with dual triodes 5687, which has excellent high-frequency response and significantly reduces distortion with increasing frequency.
3:) The 300B adopts DC filament lighting, and also uses multi turn precision adjustable potentiometers to adjust balance, with extremely low bottom noise.
4:) All levels of electronic tubes operate in Class A amplification state, resulting in minimal distortion, sweet and soft sound, and extremely high listening endurance.
5:) Adopting metal film resistors with an accuracy of up to 1% and imported electrolytic capacitors.C (capacitor) L (10H 0.3A EI76X45 choke) R (resistor) C multi-stage filtering, high signal-to-noise ratio.
6:) Adopting a 220W full power low-temperature power transformer, a 3.5K 40W copper wire wound output transformer, with strong low-frequency performance and a wide frequency response range.
7:) 5U4G rectifier tube x 1, Dawning 6N8P preamp electronic tube x 1, Toshiba 5687 push tube x 1. 300B power amplifier tube x 1 .
8:) Hand built shed, optimized layout, with minimal background noise. The cathode resistance and filament rectifier bridge generate high heat, and a large radiator is also used for heat dissipation to ensure long-term stable operation of the machine.
