Description

Feature：

* Version Option:

Volume ON tube: Volume version with ON Large triode 4281/4302

*Appearance: brushed gold panel, with professional handle, double dynamic needle indicator

*Sound quality: 20W Class A, vocals, instrument texture, low-frequency bounce ability, and air feel are all very first-class, but it is not a general Class A, general Class A over 20W will be distorted, but when A60 exceeds 20W Class A, he will Automatically extend to 200W Class A and B driver speakers to keep the speakers in good condition and dynamic.

*Technical highlights: The input and circuit are 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 pole, which can easily obtain a conversion rate of hundreds of volts per microsecond. The driving ability of the load is quite good. The output adopts 16 pairs of power tubes in parallel to obtain a very high driving force and a very low output impedance, which can easily drive a speaker of 2-8 ohms.

*Materials: 12KG full aluminum alloy chassis, luxurious head driver, as many as 16 pairs of Toshiba original 2SC5200 2SA1943 drivers, more than 2 grades better than some Class A products that only use 2 pairs of 2SC5200 tubes. The filter is 80,000UF ELNA AUDIO Japanese filter capacitor, and the total power of the dual transformer is 800W.

*The input tube is the famous fever tube 2SC2240 A970, the driver stage is the tube king 15032, 15033, the resistance is Philips non-inductive resistance, and the input terminal uses 24K gold-plated CMC, etc.

*The capacitor adopts 8 ELNA AUDIO, Japan Omron + UPC1237 protection circuit to ensure safe and reliable output and protect the speaker
