1. Handmade, the main circuit is scaffolded.
2. Two EI-type single-ended output transformers with high-grade special technology and high-quality broadband response and high quality made by Z11 core.
3. High-voltage power supply and filament power supply independently use two high-power power transformers with Z11 iron core and special materials.
4. The front stage uses two 12AX7 and 6SN7 vacuum tubes; the push part uses two 300B tubes to directly splicing to the latter stage. The tone is full and delicate, the analysis is good, the dynamic is abundant, and the atmosphere is open.
5. The latter stage uses two 805 vacuum tubes for Class A single-ended power amplification.
6, six groups of signal input (PHONO, LINE1, LINE2, LINE3, BAL ANCE, PRE IN); this machine has added a balanced input function and pure post-level function.
7, boot high voltage delay and mute delay function (about 30 seconds).
8, select Japan AL PS high-end potentiometer.
9. Easy-to-install plug-in vacuum tube protection cover.
10. Peripheral power tube bias current adjustment function and power output level meter sensitivity selection file.
