IWISTAO Single-ended Tube Amplifier 2X3.5W Class A 6N1 Drive 6P14 5Z4P Rectifier Scaffolding Soldering Solid Wood Casing AC115/220V
Model No: WVTA-6P15(S5Z)
6p14 is a commonly power output vacuum tube in the previous tube radios, with a gorgeous sound and mellow sound! Savor carefully, nostalgic thoughts emerge spontaneously. This unit is suitable for high-sensitivity small bookshelf speakers, and also very suitable for using as desktop audio and upgrade computer audio.
Since the tubes of all levels are working in Class A amplification, the distortion is small, its tone is sweet and soft.Its rated output power is 2x3.5w, but the actual undistorted output power is equivalent to 2x20w transistor power amplifier because the tube has the advantage of strong overload capability,
The casing is made of Sapele solid wood, which is medium-hardness wood that maintains original color and texture of the wood. The case is coated with environmentally friendly varnish and polished and painted many times. The texture is rich, simple and beautiful! The upper and lower top plates are painted iron plates. The advantage of using iron top and bottom plates relative to aluminum plates is that they can isolate some clutter interference. Flat proportional size, solid and steady, restrained in atmosphere. There is still space inside the casing, you can replace a larger oil-immersed capacitor, or it is convenient to rub the circuit!
Note: When testing the machine, the horn must be connected to the no-load test. It is easy to burn the transformer or the electron tube (the electron tube will appear red).
1. Manual scaffolding and welding are completed, which is convenient for upgrading and rubbing.
2. A full-power 100W EI transformer wound with high-quality annealed silicon steel sheet and oxygen-free copper enameled wire. The power margin is sufficient, the temperature rise is extremely low, and there is no heat or vibration.
3. The output transformer is wound by the winding method of 3 clips 2. The iron core is made of Japanese 0.35mm thick Z11 silicon steel sheet. The magnetic permeability of the Z11 chip will be higher, and the low frequency will be lower.
4. The non-parallel layout of the transformers can reduce the interference between the transformers to a low level and ensure that the machine has a higher signal-to-noise ratio
5. The terminal block is upgraded with pure copper and gold-plated, the power switch is 2A 250V high-quality stainless steel angel eyes with LED light switch; the volume control uses Japanese ALPS high-quality 100k double potentiometer, moderate damping, no rotating noise
6. Filtering adopts PHILIPS Philips 150uf*2, secondary filter capacitor 22UF/400V*2; with high-power metal oxide film resistors to form a crc network, it has a strong ability to suppress hum! (The bottom noise is between 3-5MV, 20cm away from the 90DB speaker can not hear the bottom noise.
7. Coupling capacitors and decoupling capacitors are dedicated for audiophiles, the sound is very mellow, and the high frequency is slim! The 100uf35v electrolytic dedicated for Japanese Ruby Audio acts as a 6p14 cathode capacitor,
