Introduction to DC-222T Dual Fax

This machine is designed based on the audio famous saying "Simplicity is the best". The circuit is simple. In addition to the current amplification output stage using transistors, the whole machine has From the front-stage input to the rear-stage voltage amplification, all is done by electronic tubes, and some circuits use direct coupling, which has better low-frequency power. The electronic tube uses the well-known 12AU7. The high-voltage power supply of the electronic tube adopts a regulated power supply with a constant current source. The regulating tube is borne by a 13007 medium power tube. It has high stability, small internal resistance and fast current supply, which brings out the excellent musical taste of the electronic tube. To the fullest. The power output adopts three-stage current amplification, and the low frequency is thick and powerful. The internal layout of DC-222T is extremely reasonable. The power transformer adopts an independent shielding interval to reduce interference to the circuit. The tube amplification part is powered by a musical R-type transformer, while the power output stage is supplied by a high-power toroidal transformer.

This machine has exquisite materials. The input selection adopts lossless relay control, the volume adopts Japanese ALPS motor potentiometer, and it also uses SOLEN and other high-grade capacitors for sound calibration.

This unit has remote control function, beautiful and fashionable appearance, and fully utilizes the excellent characteristics of vacuum tubes and transistors. The music performance is full of charming boldness, strength and speed, which is especially suitable for music lovers with elegant taste. .
