Parameters:
● PCB Size: 130 * 70mm 1.6mm
Remark:
● This version of PCB reserves two 5W voltage regulator tube package positions for series connection. If the output voltage is 200V, one 200W voltage regulator can be installed and the other bit must be shorted.
If other voltages are required, two of the same or different voltage regulators can be connected in series. If 250 VDC is required, a 130V and a 120V voltage regulator can be connected in series.
Regarding the selection of the high-voltage stabilized pressure drop:
● Since the MOS tube is used as a high-voltage setting tube, the MOS tube is better in the "small heat", and the total operating current of the bile preamplifier is generally not too large (usually around 10MA), taking into account the voltage fluctuation factors,
● It is recommended that the pressure difference is not less than 50V, and a pressure difference of 80-100V is recommended. The heat dissipation on the MOS tube has a hand warming temperature. If the pressure difference is not enough or the operating current is too low, the heat sink can be removed to warm up the GG tube. Power settings for the previous stage
● The previous stage of the GG electron tube is supplied with plus or minus 200V. In this version, the positive and negative points of the two sets of high voltage outputs of this version are shorted to ground so that they are combined to form a positive and negative 200V high voltage power supply.
● The GG electron tube uses three 12AU7 (AX7) in the preamplifier. The filament voltage of this type of tube is 12V6, 150MA. It is recommended that the filament current is not less than 500MA.
● Each group of high voltage power supply is not less than 15MA current reserve.
