6N8P+FU7+5Z3P Single-ended Tube Power Amplifier board (No tube /Transformer)

Product Description

Does not include any tubes or transformers, and can purchase tubes. Includes a power amplifier board and power board.

[sound description]
6N8P + FU7 fever tube power amplifier board, strong output power, fresh and natural sound quality, wide dynamic range, rich harmonics! It is much better than the thick and thick tube of the EL34.

【feature】
1. Use all AC filament lighting, the sound is lively, the sensitivity of the speaker is close to 90DB, you can't hear a little hum, you don't need to start the static electricity. (in the case of 5H choke)
2. The FU7 is driven by the well-known 6N8P two-stage amplifier with an output power of 9W x 2 or higher. It is suitable for speakers with a sensitivity of 88db or higher (4-8) ohms.
3. Output rated power: 9WX2 (The tube has a strong overload capability, so the actual distortion-free output power is equivalent to a 50w + 50w transistor amplifier! Since all the tubes work in the Class A amplifier, the distortion is small and the sound is very sweet. Soft and very durable!)
4. Use metal film resistors and imported electrolytic capacitors with an accuracy of up to 1%. The power filter capacitor uses a PHILIPS main capacitor and a Japanese brand sub-capacitor.
5. C (capacitor) L (choke) R (resistance) C multi-stage filtering, high signal to noise ratio.

6. Coupling capacitors use our custom TE MKP film copper foot capacitors, the sound is very round, high-frequency slim and transparent!
7. The plate tube adopts 5Z3P rectifier tube × 1,6N8P pre-stage push tube × 3, FU7 power amplifier tube × 2. (The power amplifier tube is replaced with Nanjing or European and American tubes. The three types of tubes have imported model replacement tubes, which can be purchased on Taobao according to personal preference)
8. The design of the circuit board is designed in strict accordance with the 1-point grounding principle. The thickness of copper is 1 ounce. The thickness of the copper foil is calculated from the current and the windings are as thick as possible. This is a guarantee of no noise and sufficient power. Our machines are cost-effective, PCB boards save a lot of expensive manual scaffolding, and the error rate is very low, ensuring a low failure rate. Don't spray us on diehards who like to shed. The convenience of scaffolding is to replace the original scaffolding. The impact on sound quality can be said to be negative. Customers with higher requirements can also customize gold plated plates, which can be satisfied.
10 PCB specifications: power amplifier board 250MM * 155MM, power rectification filter board 116MM * 80MM, are 1.6MM thick fiberglass board.

1pc amplify board + 1pc power board(90 days after receipt of order )
