Sound good concise 2 × 5W Danji Power Amplifier

The amplifier circuit diagram below. Amplification of cost-effective use of radio beams and tubes 4 6P1, using a dual-voltage tube to enlarge 6 N1, then into SRPP circuit, 6 N1 cathode feedback discard large electrolytic capacitor, with a 10 μ F/25V the BP capacitance, to get Lower distortion. 6P1 gate level after -11 V plus a fixed bias, 6P1 cathode only to a 3 W1 Ω cement resistors, capacitors eliminate feedback, and save big feedback loop. 

Practice has proved that this will be no greater distortion of power, a broader dynamic and very low intermodulation distortion. The two channels of the first-class and after class to share power with a filtering system can not only reduce production costs, will not reduce the channel separation. Single-channel input signal, the other did not hear any channel crosstalk, a high degree of separation. Another feature of this machine is noise (including the exchange of noise) is very low, from the Speaker 0,5 meters in places did not hear any noise. 

I used to love this machine with more CVD and a self-made air-cushion-Test-Speaker, in 15 m2 indoor-sing, sound rounded Hongliang, rich sense of space. Listen, "A Jiegu," the awesome performance, the performance of the broad sense of space to be exhaustive, Baopeng, no clutter, not power, has a powerful effects.
