Features:
1. Made by hand, the main circuit is welded by scaffolding.
2. Adopt two EI type single-ended output transformers with high-end special technology and high-quality wide-band response and high-quality made with Z11 iron core.
3. High-voltage power supply and filament power supply independently use two high-power power transformers with Z11 iron core and special material fusion.
4. Two 12AX7 and 6SN7 vacuum tubes are used in the front stage; two 300B electron tubes are directly coupled to the rear stage in the driving part. The sound is full and fine, the analysis power is good, the dynamic is abundant, and the atmosphere is open.
5. The second stage uses two 211 vacuum tubes for Class A single-ended power amplification.
6. Six groups of signal input (PHONO, LINE1, LINE2, LINE3, BALANCE, PRE IN); the machine has added a balanced input function and a pure post-level function.
7. Start-up high-voltage delay and mute delay function (about 30 seconds).
8. Use Japanese ALPS high-end potentiometer.
9. Pull-out vacuum tube protective cover for easy installation.
10. The peripheral power tube bias current adjustment function and power output level meter sensitivity selection file.
11. The sound is soft, pure and smooth, suitable for enjoying various types of music.
