Description:Tubles: 5Z4P+6N1+6P3P6p3p tube amp kit, tube amplifier.Single-ended armor class 7w + 7w output 4 ohm 8 ohm two portsThis product uses 6N1 lines constitute the input stage.Introduction to Line:1, the input voltage amplifierThe circuit has a small distortion, low noise, wide frequenc response characteristics, is one of common line of power amplifier circuit at present.2, the power output stagePower tube 6P3P standard connection, the signal from the control gate (5 feet) input, screen grid (4 feet) and power + B1 directl connected. This connection is characterized b: high amplification efficienc. To achieve the characteristics of the power amplifier tube table provided b the output power. R6 is the output stage cathode resistance, the output stage gate negative pressure determined at -19.5V. 6P3P screen voltage of 300V, gate negative pressure of -19.5v, screen flow of 60mA, for Class A amplification, the output power of about 7.5W, basicall meet the requirements of the general home environment plaback.3, the power circuitPower suppl circuit using the traditional tube rectifier, CLC-π-tpe filter,Not onl to maintain the traditional Danji musical flavor. But also to achieve harmon and balance the whole sound.B the power transformer 220v secondar output of dual 3000V voltage b 5Z4P full-wave rectifier, the output 100Hz one-wa pulsating DC b C6, L1, C7 composed of CLC-π filter to be a smooth DC high voltage. Tube rectifier in the boot process through the preheating process without high-pressure impact, with the protection of the role of the tube, which is used in the power amplifier circuit is particularl important when the price of the tube. CLC-π filter filtering effect is good, low power internal resistance, to reduce noise and improve the overall dnamic has great benefits.Package included(Complete set of componentAf
