●Output impedance for speakers: 4Ω - 8Ω
● Signal to noise ratio: 89dB
● Preamp tube :2×6J4P(or 6J8P equivalent 6SJ7,Center position for R1 and L1), 2×6N8P(equivalent 6SN7 side for R2 and L2) ● Rectifier: 5Z3P×2(equivalent 5U4G)● Power tube: 6550/KT88/EL34(depens options )
● Volume (width × height × depth): 460 × 180 × 360mm
● Net Weight: about 23Kg
● Input voltage： 50/60hz AC 110v or 230v(depend your country, we send the right version)
Feature:
● Using point to point hand-wiring,
● Power tube make for triode in parallel connection make a best sound but more powerful than signle ended amplifier
● The chassis is silver 1.2mm thick brushed stainless steel.
● increase the silver 10mm thick aluminum alloy wire drawing process front panel.
● Add a silver 6mm aluminum alloy wire drawing process rear panel.
● increase the aluminum alloy wire drawing process cattle cover.
● The black aluminum alloy knob is changed to a silver-white drum type aluminum alloy knob.
● The volume control is changed from Taiwanese W.L or Elf potentiometer to 27 type blue shell sealed step potentiometer.
● The default two-way signal input is directly increased to four-way signal input.
● The power switch is changed from ship type to rotary type.
●consider the luxury version of the appearance of coordination to remove the red cherry wood decorative board on both sides.
●The first stage of amplification uses the hexapole 6J4P (or 6J8P) for amplification. The chromaticity of the pentode is gorgeous, and the single-stage gain is high. The unit is connected to the triode to amplify the lens, further reducing the distortion and making the tone more delicate.
● The second stage promotes the use of twin-stage three-stage tube 6N8P internal parallel push. The maximum anode dissipated power of 6N8P can reach about 6W, and the internal resistance is lower after parallel connection, and the driving force is better.
●The rectification adopts the high-current rectifier T-type hook filament 5Z3PA×2 secondary rectification method, which makes the high-current supply of Class A amplification better and more abundant.
