Read More…Power Supply Voltage: defaults double AC 18V/3A, power more than 60W (the maximum voltage should be no more than double AC 19V, and it should be no less than 18V; or the digital tube will be off, and the voice will get distorted; if you want to use AC 12V, you need to modify lamp filament buck resistance 2.2 ohm; then the amplifier output power will be relatively low).
Headphone amplifier/pre-output: amplification times is 0.8
Im1875t amplifier output power: typical 20W (max 30W)
Loudspeaker impedance: 4-8 ohm
Total harmonic distortion: <0.04%
Signal noise ratio: 105dB
Frequency response: 14Hz-100KHz
