Stand Version Option:

EL34 Version: the power tube is EL34, (replace power tube is EL34, 6CA7, KT66, 6L6), using PCB inside design;
KT88  Version: the power tube is PSVANE KT88 , (replace power tube is KT88, 6550, KT90), using PCB inside design;
6550 Version: the power tube is 6550 , (replace power tube is KT100, KT88, KT90),  using PCB inside design; 
FU50 Version: the power tube is FU50 ,  (replace power tube is Russian GU-50 or Germany LS-50 ), using PCB inside design; ( this model just have the standard version )

 

Stand Version  Technical parameters:
● Output Power per channel: 20w/EL34, 30w/KT88, 35w/fu50 ( only with triode connection mode)
● Frequency response: 20Hz~30kHz ±1db
● Total harmonic distortion: < 1% (1kHz)
● Input sensitivity: 500mV
● Input impedance: 100KΩ
● Output impedance for speakers: 4Ω - 8Ω
● Signal to noise ratio: 89dB
● Preamp Tube: 12AT7×2(center position for R1 and L1), 12AU7×2(side for R2 and L2), 6N6T×2(longer side for R3 and L3)
● Rectifier: 5Z3P×2
● Power tube: 6550B/KT88/EL34-B/FU-50 (depens options )
● Volume (width × height × depth): 460 × 180 × 360mm
● Net Weight: about 26Kg

Stand Version  Feature:
● The power supply cattle and output cattle are made of imported high-grade silicon steel sheets and layered inter-stage winding technology. Power burdock steel: 114mm × stack thickness 60mm, output burdock steel: 96mm × stack thickness 40mm. High quality nylon skeleton, high purity oxygen free copper wire.
● Using WIMA red MKP polypropylene capacitive coupling.
● Use carbon film resistors. Although the error and thermal noise of the carbon film resistor are slightly larger than the resistance of the metal film, everyone recognizes that the sound of the carbon film is warmer. The actual thermal noise carbon film is also almost indistinguishable from the gold film. Considering the warm tone, the default printed circuit board model of this machine uses carbon film resistors, and the scaffolding welding machine uses military Dahongpao gold film resistors and carbon film mixed.
● Rectifier part, high voltage adopts secondary rectification technology, 5Z3P×2 bile rectification, 4 high quality large ponds and 2 inductive filters.
●Refer to the classic line improvement, 12AT7×2 voltage amplification, 12AU7×2 inversion, 6N6×2 cathode output push, push-pull AB amplification. The frequency response is wider, the phase shift is smaller, and the fidelity is higher.
● Transformers are processed by potting methods commonly used by most manufacturers to provide insulation, moisture, shock absorption, etc., which can greatly reduce the magnetic coupling through the chassis, reduce resonance and reduce noise.
