All items ONE-YEAR WARRANTY !!!
We can Declare the Value of the Order as Customer's Remark!!!
Features of this machine:
●Made by hand, the whole machine adopts scaffold welding
●Using two high-quality wide-frequency response and high-sound quality EI output transformers
●The front stage uses two 6H2C and 6N7P vacuum tubes each
●The rear stage uses four KT88 vacuum tubes to do AB1 push-pull power amplification
●Easy to install pluggable vacuum tube protective cover
● Peripheral power tube current adjustment knob and current display meter
●Infrared remote control
●Power-on mute delay function (about 20 seconds)
●Select Japanese ALPS motor potentiometer
●Increase the power output transformer 60W+60W
●Adopt the audio frequency resistors produced by US Visa and Philips
●Appearance treatment uses high-end automotive paint technology
●Provide triode and super linear selection function. The triode working mode has a soft, pure and sleek sound, suitable for listening to vocals, strings and other types of music; the super linear working mode, the sound is open, unrestrained, and vigorous, suitable for enjoying large scenes, large dynamics and other types of music.
