Local features :

1. Made purely by hand, the main circuit is constructed using shed welding.

2. Two EI type single ended output transformers made with Z11 iron core, featuring high-end special craftsmanship and high-quality wideband response.

3. High voltage power supply and filament power supply independently use two Z11 iron cores and a high-power power transformer fused with special materials.

4. Two 12AX7 and two 6SN7 vacuum tubes are used in the front stage; The driving part adopts two 300B electronic tubes directly coupled to the rear stage, with a full and delicate tone, excellent analytical power, abundant dynamics, and a grand atmosphere.

5. Two 805, 845, or 211 vacuum tubes are used in the later stage for Class A single ended power amplification.

6. Six sets of signal inputs (PHONO LINE1 LINE2 LINE3 BALANCE PRE IN) ; This machine has specially added balanced input function and pure back-end function.

7. Power on high voltage delay and mute delay function (approximately 30 seconds). 8. Choose the Japanese ALPS high-end potentiometer.
