Features: 

• Pure hand-made, Point to point manual welding. 

• Use a square power transformer specially developed for this machine. 

• The output transformer uses two high quality wideband EI output transformers. 

• The preamp stage uses one 6SN7 for power supply filtering. 

• The voltage amplification stage and the push stage use two pairs of 6SL7 and 6SN7 tubes, respectively. 

• The power amp stage uses KT88 tubes for class AB Push-pull power amplification. 

• Triode and ultra-linear selection are available. The triode works in a soft, pure-and sleek sound, suitable for listening to vocals, strings and other types of music. Ultra-linear working mode, sound-tone open, unrestrained, good momentum, suitable for enjoying big scenes, big dynamics and other types of music. 

• External independent BIAS-ADJ current display header. Adjustment and BIAS meter monitoring function keeps the best state of the power tube at all times. 

• External KT88 tube selection function, easy to replace different types of tubes, adding endless fun. 

• Infrared full-featured remote control. 

• Use thick silver plated signal leads. 

• With pure post-level function, it can be connected to independent preamplifier signal input. 

• Power on mute delay function (about 30 seconds). 

• Select Japanese ALPS high-end motor potentiometer. 

• Easy-to-install plug-in tube cage cover.
