Power supply for Pre, Phono, Loudspeakers .. Audio system is very important, it is the power supply factor and feeds the whole audio system. Not only that, power is also a key factor in determining the output audio quality. Basically, it must be clean enough so that the system does not have a lot of noise.
Hq-Audio has succeeded in using and designing voltage sources for audio systems such as Pre, Phono, DAC, Amplifier …,The Hq9038-HV regulator is one of the high voltage voltage regulators designed for preamplifiers using the Tube with the following features:
♥ Input: 130 V to 350 VDC.
♥ Input Voltage and Min Output Voltage 35V.
♥ The output voltage is controlled by the Vr1.Vr2, Vr3 variable.
♥ Noise below 10uV.
♥ Very good PSRR reaches 160dB (60khZ – 100kHz).
♥ Output impedance: 0.03 mOhm.
Low Supply : 6 to 12VDC
♥ Filemant Tube: 6.3VDC to 12VDC/ 3A
