Features of the machine
1. It is made by hand, and the whole machine is welded by scaffolding2. Two Japanese E-type output transformers with high quality, wide frequency response and high sound quality are used3. Use high power Z11 core ring power transformer specially designed for this machine4. In the high voltage part, two dawning 274b vacuum tubes are used for full tank rectification. 5. Two Czech 65l7 and 6sn7eh vacuum tubes are used in the front stage, and two 3008 vacuum tubes are used for class a single ended power amplification6. Peripheral power transistor current adjustment button, current display and dynamic output level UN meter7. Japanese APS motor potentiometer and German mondorf MCAP heating capacitor are used8. Power on mute delay function (about 30 seconds)9. Infrared remote control10.
