Rectifier Filter Power Supply Board 7a Adjustable Voltage Tube Amplifier Filament Voltage Regulator Ac 35v

It is a linear step-down module. Although the voltage adjustment range can be adjusted from 2.5V to 37V, it is recommended that the working pressure difference be within 10V, because the power consumption is proportiol to the pressure difference.
If the output voltage is required to be 24V, the ideal DC voltage before stabilization is 26V, and then it is converted into an AC formula (26Vdc / 1.4 times = 18Vac), so an 18V output transformer is ideal.
The circuit board of this product is made of high-quality 1.6mm double-sided glass fiber board, double-sided wiring, and tin-plating process.
The main filter capacitor pin is equipped with a "lead pin/hard pin" coexistence design, and the diameter of the capacitor is a filter capacitor of 23mm.
The layout adopts the classic single-point grounding, all grounding wires are copper wires, and the components are arranged symmetrically, which is beautiful and generous.
