Sunbuck 12AX7 6C19 Vacuum Tube Amp Tube Headphone Amplifier HIFI Preamplifier 0 noise Tube Amplifier Audio
DIY Kit: Buyers are required to solder by themselves
The pure vacuum tube (vacuum tube rectifier) headphone amplifier assembled and debugged with the fever concept can also be used as a HIFI preamplifier, with excellent results! ! !
Product parameters:
1. The filament of the electronic tube is powered by 3.15V-0-3.15V AC, which makes the sound quality more charming. At the same time, the noise floor of the whole machine is only a weak 4MV, which is the embodiment of the designer`s profound skills.
2. Frequency response range: 20HZ-28KHZ
3. Signal-to-noise ratio: 97DB
4. Any headphones that support impedance above 16 ohms!
product description:
1. Standard electronic tube: rectifier tube Dawning 5Z4P amplifier tube: 1 Dawning 12AX7 (pre-stage tube can be directly replaced by 12AT7, 6N4, 12AU7), 2 Beijing 6C19. The vacuum tube has a strong flavor, the vocals are mellow, tough and bouncy!
2. High-quality Japanese-made output coupling capacitors, German Vishay and Red WIMA inter-stage coupling capacitors, and South Korea`s SAMYOUNG large-capacity capacitors are used as filter capacitors.
3. The signal path adopts pure copper wire, and the RCA terminal adopts copper gold plating. Lay the foundation for high-quality transmission of audio signals. The material of the power socket is: nickel-plated copper.
4. All low-power resistors are made of domestic precision metal film copper pin resistors, with high signal-to-noise ratio, good stability and high precision. High-power cathode resistors use aluminum shell resistors.
5. Using Japanese ALPS 16 potentiometer, there is no noise of other brand potentiometers, and it has a long life and durability.
6. Use 5H large inductance choke coil (No. I572413) to filter to ensure that the current is clean, the background is also clean, and there is no noise! Although the cost of the whole machine is about 50 yuan higher, it is worth it. The annoying thing about using amps is the noise! Power transformer 2 (code 764202) has a total power of 80W, is made of high-quality annealed silicon steel sheet, and has a low temperature rise for long-term use (generally not exceeding the ambient temperature of 20 degrees), and is made of pure copper enameled wire.
7. The high-quality sapele wood case, not the skinned one, has changed the cold style of the stainless steel case and the aluminum case, and the electronic tube is full of warmth. Perfect for you who are traditional and nostalgic! Chassis, size: width 200MM height 135MM (including chassis feet to the top of the tube) depth 300MM (excluding knob protrusions). Weight 4KG.
8. The PCB is a 1.6MM thick double-sided board and a thick copper plate. The design strictly follows the principle of one-point grounding. The layout of the wiring in the box is reasonable and orderly. The power lines and signal lines do not overlap and overlap, effectively reducing the probability of mutual interference!
9. The bottom of 6C19 and 12AX7 is equipped with blue LED light, and the effect of turning on at night is very beautiful. Antique aluminum-plastic large knob, angel eye with LED light stainless steel button switch, copper gold-plated contact headphone socket.
