6N1 6P3P EL34 tube amplifier 7w + red walnut case finished machine or kit mellow tone | Обустройство дома

【Material Description】1. The default potentiometer is ALPS 16 type2. Standard equipped with Dawning 5Z4P rectifier tube, and also compatible with 5U4C, 5AR4, 5Z3P and other rectifier tubes.3. 66 * 44 Z11 iron core, 8W output transformer wound with high-purity copper wire. The output transformer is wound by 3 clips 2 winding method, and the iron core is made of new Japanese 0.35MM thick Z11 silicon steel sheet.4. Pure copper gold-plated RCA lotus socket and large copper gold-plated speaker terminal.5. The filter capacitor adopts Japanese electrolysis, combined with high-power metal oxide film resistor and 5H choke to form a clrc network, which has a strong ability to suppress hum!6, 5H 200MA fully shielded shell inductance, small magnetic leakage, a weapon to contain noise.7. It is easy to install with PCB welding. PCB thickness 1.6MM, 1 oz thick copper double-sided board. Strictly follow the design of one point grounding principle, the layout of the wiring is reasonable, the noise floor is minimal, and the peak value does not exceed 4MV.8. The electronic tube seat is a copper silver plated ceramic tube seat.9. The coupling capacitor is a Hong Kong film antique capacitor. The sound is very mellow, the high frequency is slim, the style is similar to WIMA, but it is not as bright as WIMA!10. The terminals are gold plated with pure copper.11. The volume knob is aluminum-plastic 36MM C2 with scale knob, and the power switch is 10A 250V high quality and durable toggle switch! The switch lever is horizontal.12. A wooden frame chassis made of red walnut logs, 20MM thick, strong and beautiful, retro style, 2MM aluminum plate on the top, 1MM punching paint iron plate on the bottom13. Size and weight: moderate volume (25cm wide, 30cm deep, 19cm high). Flat proportion size, heavy and steady (8.2KG), restrained atmosphere!15. The rated output power of the machine: 7w + 7w tube has the advantage of strong overload capacity, so the actual undistorted output power is equivalent to the 50w + 50w transistor amplifier!This machine has two impedance output modes of 4 ohm and 8 ohm. This machine is suitable for the selection of small bookshelf speakers with high sensitivity. It is recommended that the 6.5-inch 80W power box is more suitable. The full-frequency paper tray speaker speaker does have another charm when listening to human voices. It is a perfect match with our full-frequency 5.5-inch box. Since the tubes at all levels work in the Class A amplification state, the distortion is small, the sound is sweet, soft, and the hearing resistance is extremely high!16. For safe mailing, the shop uses thick packaging, and the electronic tube is also individually packaged, and you plug it in after arrival!
