Machine 220v resistance with a new component
This is DIY KIT, you need to solder it by yourself.
Tubles: 5Z4P+6N1+6P3P
6p3p tube amp kit, tube amplifier.
Single-ended armor class 7w + 7w output 4 ohm 8 ohm two ports
This product uses 6N1 lines constitute the input stage.
Power amplifier level 6P3P standard connection, 6P3P for the entry-level products,
Line design is reasonable, well-produced, but also play to the realm of fever 6P3P.

Introduction to Line:

1, the input voltage amplifier
The circuit has a small distortion, low noise, wide frequency response characteristics, is one of common line of power amplifier circuit at present.
2, the power output stage
Power tube 6P3P standard connection, the signal from the control gate (5 feet) input, screen grid (4 feet) and power + B1 directly connected. This connection is characterized by: high amplification efficiency. To achieve the characteristics of the power amplifier tube table provided by 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, basically meet the requirements of the general home environment playback.
3, the power circuit
Power supply circuit using the traditional tube rectifier, CLC-π-type filter,
Not only to maintain the traditional Danji musical flavor. But also to achieve harmony and balance the whole sound.
By the power transformer 220v secondary output of dual 3000V voltage by 5Z4P full-wave rectifier, the output 100Hz one-way pulsating DC by 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 particularly 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 dynamic has great benefits.
