• Independent mono balanced transmit amplifier structure.
• The audio signal input stage uses ECC88/6DJ8 electronic tube for gallstone hybrid differential voltage amplification, and famous transistor for the second stage and then differential voltage amplification;
• The final stage consists of 24 high-power transistors to form a powerful power output stage.
• The power supply part consists of a 1500W toroidal transformer and a 120,000 microfarad audio electrolytic capacitor.
Equipped with a working status indicator, it can be clearly observed that the machine is in the operating state of Class A or Class A and B.
• Class A output status within 100W
When it exceeds 50W, it will automatically switch to Class A and B output mode to save energy and save power, and it is also powerful when playing large dynamic music.
•The audio signal input stage is made of electronic tube for differential voltage amplification. The famous transistor is used for the second stage of differential voltage amplification. The final stage is composed of 24pcs high-power transistors to form a powerful power output stage.
