Features:

1: The whole machine adopts high-quality PCB welding to ensure stability and integrity

2: Two EI output transformers with high-quality wide-frequency response and high-quality Japanese Z11 iron cores are used

3: Use a toroidal power transformer specially designed for this machine.

4: The pre amplifier uses two ECC82 vacuum tubes.

power amplifier uses two KT88 vacuum tubes for class A single-ended power amplifier.

Among them, the tetrode KT88 circuit adopts the working mode of the tetrode,

Fully embodies KT88's unique and vigorous personality.

5: Input has BALANCE/RCA/Bluetooth selection.

6: Headphone output can choose four-core balanced output, 4.4 and 6.35 head output

7: With external speaker function

8: Power-on mute delay function (about 30 seconds)

9: The volume potentiometer selects the Japanese ALPS (Alps) potentiometer

10: Easy-to-install plug-in vacuum tube shield.
