Description: Introduction: ● Sound quality; Magnificent, 20W pure class A, vocals, instrumental texture, low-frequency bounce, air sensation is very first-class, but he is not a general class A, generally more than 20W will be distorted, but A60 when more than 20W pure class A, It Will automatically extend to the 200W Class AB drive speaker, keeping the speaker in good condition and very dynamic. ● Technical highlights; The input circuit is a fully symmetrical architecture, current feedback. The main feature of this circuit is that it uses a complementary push-pull circuit from the input stage to the output stage. It can easily obtain a conversion rate of hundreds of volts per microsecond and drive capacity for capacitive loads. Quite good, the output uses 16 pairs of power tube parallel outputs for very high driving force and very low output impedance, easily driving 2-8 ohm speakers. Input voltage: AC 36V-0-36V, 36V-0-36V (Not less than 300W) Auxiliary protection voltage: AC 0--12V, 0--12V (Not less than 10W) Class A output power: 20W 8ohm Class AB output power: 200W 8 ohms, 400W 4 ohms Recommended output tube model: 2SCA1943/2SC5200 Distortion: 0.002% Signal to noise ratio: >100dB Frequency response: 5Hz---40KHz PCB size: 272mm * 88 mm NOTE: This is a Bare PCB, and all parts need to be matched by yourself.
