Description:
The PCB size is 130*70mm with a thickness of 1.6mm and a tin spraying process. On the PCB, there are two reserved positions for two 5W regulator tubes that are connected in series. If the output voltage needs to be 200V, one 200W regulator can be installed in one position while the other position needs to be short-circuited. For other voltages, two regulator tubes of the same or different voltages can be used in series. For example, if 250VDC is required, one can use a 130V and a 120V voltage regulator tube in series.
When choosing high voltage stabilized voltage differences, it is important to consider that using a MOS tube as a high-voltage voltage regulator tube results in a better listening experience with "small warmth". Given that the overall working current of the bile pre-stage is usually around 10MA and voltage fluctuations must be taken into consideration, it is recommended that the pressure difference should not be less than 50V, with a suggested range of 80-100V. The MOS tube should have a warm hand temperature for optimal heat dissipation.
In terms of the power setting of the GG tube front stage, it is powered by plus and minus 200V. To combine the two sets of high voltage outputs into a plus and minus 200V high voltage power supply, the positive and negative points between them should be shorted to the ground wire. The GG tube front stage uses three 12AU7 (AX7) tubes with a filament voltage of 12V6 and 150MA. It is recommended that the filament power supply current is not less than 500MA and each group of high-voltage power supply should have a current reserve of at least 15MA.
The packaging includes 1 GG-PSU High-voltage Dual-channel Stabilized Voltage + Filament Stabilized Power Supply KIT Dual 280VPCB with dimensions of 13070mm and a thickness of 1.6mm with tin spraying process. The kit includes the necessary components for a high-voltage dual-channel stabilized voltage and filament stabilized power supply solution.
