35V 4700uF Parameter Description: 

Product Advantages:
Use 25A flat bridge rectifier! Directly turn 4 lanes into 16 lanes, so that the current of this power module can reach 10A! The pond is limited, and there is no point in increasing the current!
4 0.1uf Brexit capacitors! There are only 2 ordinary power modules, only in front of the filter capacitor, and we have both in the front and the rear of the filter capacitor. The front eliminates the fluctuation of the rectifier bridge, and the rear eliminates the high-frequency clutter of the power supply, and the quality of the power supply is better!
4 35V4700uf or 50V3300uf electrolytic capacitors!
More compact PCB layout! Easier to DIY!
The 35V4700uf version is suitable for the output voltage not exceeding ±35V. The output DC voltage is about 1.4 times the input AC voltage. For example, if the input AC 18V, the output is ±25V, and the input single/double AC will output DC positive and negative dual voltages.

50V 4700uF Parameter Description: 

Product Advantages:
25A full-wave rectification, and use 4 large electrolyzers to form a filter array, great dynamics! High Power! All in all! More responsive! Let the power amplifier board retract freely! Raise the upper limit of sound quality!
The full-bridge rectifier will boost the voltage by about 1.4 times. For example, the AC input is 12V, and the output is about DC ±17V. The 50V version is suitable for situations where the output voltage does not exceed ±50V. The output voltage of the transformer will fluctuate with the fluctuation of the mains. In actual use, do not test the upper limit of the power supply, and be sure to leave a margin! If the voltage rises, it will likely cause the capacitor to explode! Especially the electrolysis with small volume and large capacity like 35V10000uf.

 
63V 3300uF Parameter Description: 

Product Advantages:
5A full-wave rectification, and use 4 large electrolyzers to form a filter array, great dynamics! High Power! All in all! More responsive! Let the power amplifier board retract freely! Raise the upper limit of sound quality!
The full-bridge rectifier will boost the voltage by about 1.4 times. For example, the AC input is 12V, and the output is about DC ±17V. The 63V version is suitable for situations where the output voltage does not exceed ±63V. The output voltage of the transformer will fluctuate with the fluctuation of the mains. In actual use, do not test the upper limit of the power supply, and be sure to leave a margin! If the voltage rises, it will likely cause the capacitor to explode! Especially the electrolysis with small volume and large capacity like 35V10000uf.
