Features:  Working principle and characteristics:  Linear17 is a special audio-specific regenerative power supply that produces a perfect sinusoidal AC voltage from a DC voltage, which is amplified and expanded to form the same AC voltage output as the mains.  The traditional regenerative power supply usually turns the input mains voltage into a direct current, and then converts it into a direct current by DC conversion. In theory, no matter how serious the interference pollution...

Features: a) Using 12BH7 of low internal resistance and pingtung consumption to replace 6N8P,for long-tail inverted push,and the final stage is ultra-linear power amplifier tube connection. b) Use the self-bias mode, easily for tube replacement, without adjustment, which is suitable for the modern lifestyle. The machine adopts the tube and transistor hybrid rectification in the high-pressure part. c) Adds negative feedback winding, phase-frequency characteristics has more superior performance...
