2x12W Single-ended Pure Class A Tube Amplifier HIFI 6N2J Preamp  EL34 Power Amp 5Z4PJ Rectifier Mirror Stainless Steel Chassis Silver 

Model No: WVT2018



1. Pre-amplifier: 6N2J × 2.

2. Power amplifier of output tube: EL34B × 2.

3. Rectifier tube: 5Z4PJ × 1.

4. Power transformers:

A. Use 0.35, 96-60 large power core manufacturing, design power of 200W to ensure adequate power and low temperature rise.

B. Use high-quality oxygen-free copper enameled wire enameled layered tightly wound, with extremely low no-load current characteristic, quiet operation, no vibration, no hum.

5. Output transformer:

A. Use potting output transformer with 0.35 thick high-flux silicon steel (76-40) to ensure stability and reliability, especially in damp places, have a more reliable performance;

B. Output transformer, is high-purity copper wire enameled wire package, and layered segmented string and connection method, three clips two wound;

C. Divided into sub-fine tightly wound, with Japan's ultra-thin electrically insulating paper of pure wood (thickness of only 0.06MM, withstand voltage 2000V). Using the classical input series, parallel output characteristics, to make up for high output transformer inductance, low leakage characteristics.

D. Housing of output transformer with high-grade stretch cover, surface temperature paint handling, and bright fringes processes.

6. Use ALPS potentiometer

7. Capacitance:

A. Use imported HIFI capacitor filter capacitor (Japan ELNA, Japan Ruby, etc.).

B. Coupling capacitances adopt HIFI-class audio-specific capacitors; sound transparent is elegant, passionate.

9. Audio output terminals adopt high-grade gold-plated sockets with a transparent cover.

10. Whole amplifier circuit

A. adopt Japanese SUN classic lines improvement, every channel uses 2pes three common cathode tube parallel amplification with high output voltage.

B. has characteristics of driving current, full sound fast, transparent treble and smooth.

C. Adopt high-voltage full-wave rectifier tube dual with 315V +315 V, import core power inductors,  ?-type power supply filtering, import Philips / ruby supply filtering.
