Nobsound HiFi Vacuum Tube Amplifier

The amplifier offers a power output of 4W x 2 (standard connection), making it suitable for speakers with a sensitivity of more than 90dB. The frequency response range is 20Hz to 20KHz, and the input voltage can be either 100-120V or 220V-240V at 50Hz/60Hz.

The main transformer power is 75W, and the output impedance is compatible with both 4Ω and 8Ω speakers. The power transformer specifications are 76 * 40 230V 0.15A, with 3.15V * 2 3A 75W. The output transformer is 5k 66 * 32 8W.

Physically, the amplifier has dimensions of 328 * 176 * 52mm (12.9 * 6.92 * 2.04 inches) and a net weight of 4kg (9.92 lbs). The package weight, including accessories, is 5.5kg (12.12 lbs). The package includes the amplifier and a power cord.

The power stage and input voltage amplification stage employ 6N2 and 6P1 tubes, ensuring low distortion, low noise, and a wide frequency response. The standard connection method provides high amplification efficiency.

The power circuit utilizes a vacuum tube rectifier, which has a low internal resistance power supply, offering significant benefits in reducing noise and improving dynamics. This design not only preserves the musical charm of tube amplifiers but also delivers a harmonious and balanced sound.

The overall sound quality is pure, mellow, delicate, and sweet, with excellent control over the connected speakers.
