Power tubes have: KT100 KT88 6550B EL34-B FU-50 to choose.

1.Since the class A amplifier operating point is selected on the line segment characteristic curve , so a relatively small nonlinear distortion , even harmonic content, but also very good sound effects , sound quality beautiful moist , sweet and pleasant , quite " multi- harp " rhyme sense . But lower efficiency, lower output power , high sensitivity requirements of the speakers .
2.In order to solve the low-power single-tube Class A output , with difficult issues, the amplifier output power tubes in parallel , reducing the output impedance , and enhance the driving force.
3.The machine uses an ancient handmade scaffolding welding process.
4.The first stage amplification using pentode 6J4P ( or 6J8P) for amplification, pentode tone sounds gorgeous , single-stage high gain, the native form of this pipe connected to the transistor amplification , further reducing distortion , making the sound more delicate.
5.The second stage to promote the use of twin dual triode 6N8P internal shunt promote , 6N8P maximum anode dissipation power up to about 6W, lower the parallel resistance , better driver .Rectifier with large current rectifier 5Z3P × 2 secondary rectification methods, making the CPI amplified by the large current supply better and more abundant.
