Single-ended Tube Amplifier 2X3.5W Class A 6N1 Drive 6P14 Upgrade Version Retro-style Willow-wood Casing Scaffolding Soldering HIFI DIY
Model No: WVTA-6P14(S)
Tube 6p14 is commonly used in tube radio power as output power tube before transistors was used, its sounds gorgeous, mellow! Savor, nostalgic thoughts spontaneously! Particularly suitable to enjoy the vocal-oriented for you!
Between tubes and speaker, the coupling output transformer are used at this tube amplifier, showing the layout of a triangle that transformer arrangement can minimize mutual interference, to ensure that the unit has a high signal to noise ratio. It is very suitable for using as a desktop computer and upgraded stereo sound. Since the tubes of the unit all work in class A amplified state, its distortion is lower, and sound sweet, soft!
This unit is suitable for matching with small high-sensitivity bookshelf of course matching with speakers, full-range speaker is perfect. Because tube has overload strong advantages, its actual power output without distortion is quite with the output of 2x20w transistor amplifier.

Inside View (To prevail in kind)
Only for you information, the photo below don't include the oil coupling capacitors and choke coil.
Features
- Fully scaffolding hand soldering by manual.
- Willow wooden chassis by handmade DIY that dried will not crack, after then repeated polishing painting, rich textures, simple and beautiful! Unique in the world!
- 3MM thick aluminum top plate and the bottom plate is 1MM thick aluminum one, the benefits of using a metal top plate and bottom one can be isolated portion of clutter!
- Adapt an enough 75W power transformer power, it is not able to be hum and over hot. With horizontal installed and no cover, it all seems a work of art. Winding method of Output transformer use 3 folder 2 winding, the core is made of new Kawasaki 0.35MM thick Z11 silicon steel sheet whose permeability is higher, low frequency of this unit will be lower.
- Coupling capacitors and decoupling capacitors using German WIMA MKP dedicated hi-fi capacitors; sound is very mellow, high-frequency thin! Japanese audio-specific 330uf35v ruby electrolytic capacitor cathode served tube 6p14.
- The power rectifier adapts transistor rectifying plus tube buffer circuit that can protect the tubes. Filtering capacitors use Phil ips 150uf * 1, Japanese chemical 47uf * 1; 22ufx2 High Voltage.
-
Uprade version:
- With gold-plted tube base sockets all.
- With the power and cement resistors 5H choke coil, they compose a clrc network that have a strong immunity capability to hum.
- Volume control adapt quality Japan ALPS double 100k potentiometer, damping is moderate, no rotation noise.
- There is room inside the chassis, you can replace a larger volume of oil capacitors or easy to DIY the circuit as you like.
