This is a Power Amplifier too (there is a group pre-amp input).


All items guaranteed 100% BRAND NEW in the original edition Box.


Hand welding point to point, the main circuit adopts shed welding
Two high-end EI type single-ended output transformers with high-end special technology and high-quality broadband response made of Z11 iron core
High-voltage power supply and filament power supply independently use high-efficiency toroidal, high-power power transformers with Z11 cores and special materials.
The front stage uses one 12AX7 and two 6SN7 vacuum tubes; the driving part uses two 300B electronic tubes to amplify the rear stage.
The front stage uses a 5U4G for rectification
The rear stage uses two 845 vacuum tubes for class A single-ended power amplification
Five groups of signal input A, B, C, (D) BALANCE, E (PREIN) This machine is specially equipped with balanced input function and pure rear function
Power-on high-voltage delay and mute delay function (about 30 seconds)
Infrared function remote control
Use Japanese ALPS high-end potentiometer
Easy-to-install plug-in vacuum tube shield
