product details
1. 805 uses DC filament lighting, closely attached to a horn with a sensitivity of 90DB, with only a slight AC background noise.
2. The well-known 6P6P (6L6, EL34, 6P3P, 5881, KT66 can be directly replaced) power transistor is used to drive 805, with an output power of over 45W × 2. Suitable for speakers with impedance above (4-8) ohms and sensitivity above 88db.
3. Rated output power: 45W * 2 (Due to its strong overload capacity, the actual undistorted output power of the electronic tube is equivalent to that of a 120w+120w transistor power amplifier! Since all levels of electronic tubes work in Class A amplification state, the distortion is small, the sound is sweet, soft, and the listening tolerance is extremely high!)
4. A large number of high-precision imported high-temperature copper foot resistors and imported electrolytic capacitors are used, and the power filter capacitors are made of Nippon Chemical or Ruby. The potentiometer adopts the Japanese ALPS 27 type, with a solid aluminum volume knob diameter of 38mm.
5. C (capacitor) L (5H 0.2A choke) R (resistor) C multi-stage filtering, high signal-to-noise ratio.
6. Adopting a 640W full power low-temperature copper core power transformer; Output transformer made of 80W Japanese Z11 iron core
7. The coupling capacitor adopts high temperature MKP thin film capacitors such as TE from Tokyo Electronics and Nippon Paint from Japan.
8. The machine comes standard with 2 noble ECC82 preamp tubes, 2 Shuguang EL34 push tubes, and 2 Linlai 805 power tubes.
9. Manual point-to-point welding, optimized layout, with minimal background noise. The cathode resistance and filament rectifier bridge generate a lot of heat, and a large radiator is also used for heat dissipation to ensure long-term stable operation of the machine. The power switch is a Taiwan made copper handle silver contact long-life toggle switch. RCA sockets and terminals are made of pure copper and gold-plated.
10. Machine dimensions: width 500MM, depth 360MM (excluding horn terminals and knobs), height 290MM (including electronic tube and foot pad height).
11. The machine panel is equipped with a 45mm diameter current indicator head,
12. Weight: 28 kilograms. The materials we use, such as transformers, are all genuine. The transformers are all exposed without glue or covers, and everything can be seen, so the effect can be imagined
13. Chassis material: Both the top and bottom plates are made of 1.5mm thick iron plates, which have good heat dissipation effect; Wooden panel made of black walnut wood,
