Features of this machine:
1. Purely handmade, the whole machine adopts scaffold welding
2. Use two Japanese high-quality, wide-frequency response and high-sound quality EI output transformers
3. Use EI type power transformer specially designed for this machine
4. The front stage uses 2 12AX7 and 12AU7 vacuum tubes each, and the rear stage uses 4 EL34 vacuum tubes for AB1 class push-pull power amplification, providing triode and ultra-linear selection functions. Three-stage tube working mode, the sound is soft, pure and sleek, suitable for listening to vocals, strings and other types of music; ultra-linear working mode, the sound is open, unrestrained, and vigorous, suitable for enjoying large scenes, large dynamics and other types of music .
5. Peripheral power tube current adjustment knob and current display meter.
6. Infrared remote control.
7. Power-on mute delay function (about 30 seconds).
8. Choose Japanese ALPS high-end motor potentiometer.
9. Plug-in vacuum tube protective cover for easy installation.
