Features:

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

2: Use two E-type output transformers with high-quality wide-frequency response and high-quality Japanese Z11 iron cores 3: Use a toroidal power transformer specially designed for this machine

4: The front stage uses 12AU7 vacuum tube X2

The latter stage uses EL34 vacuum tube X2 for class A single-ended power amplification.

Among them, the working mode of the triode is used in the pentode EL34 circuit.

Fully embodies the moist and thick personality unique to EL34.

5: Input has BALANCE/RCA/Bluetooth selection.

6: Headphone output can choose four-core balanced output and 6.3 head output

7: Equipped with external speaker function, start mute delay function (about 30 seconds)

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

9: Easy-to-install plug-in vacuum tube shield
