This machine circuit features:

1: The front stage is "SRPP" circuit, with wide frequency response and low output impedance

2: The post-stage amplification is a high-power triode (845) with low internal resistance, and it is a class-A single-ended amplifier.

3: The post-stage push circuit is a "SRPP" circuit, and it is a double-tube parallel connection. Wide frequency response and strong thrust.

4: The output transformer adopts the audio frequency oriented silicon steel sheet Z11 (035mm thick) imported from Japan and oxygen-free copper high-strength enameled.

5: The wire and special winding process are layered and grouped, so that the frequency response of the machine is wide, and the high, medium and low frequency sound of the machine is guaranteed to be good, transparent and powerful.

6: This machine is made of high-precision electrolytic and non-polar (MKP) capacitors and high-precision gold resistors.

7: The main channel uses audio Japan imported (ALPS) volume motor potentiometer.

8: The high-voltage power supply is controlled by automatic delay power-on, which can effectively prolong the life of the vacuum tube, and has a full-function remote control..

9: Use a large VU meter for volume indication.

10: ach channel uses 20,000f, and the large pond capacitor with a total of 40,000f for two channels is used as a DC wave filter circuit..

Electricity to the filament makes the machine extremely low noise and better sound quality.
