One Pair A1000 Music Fidelity 2.0 Channel Class A HiFi Power Amplifier Board
Characteristic:
1. Adopt original ON-MJE15024/MJE15025
2. The five-ring metal resistor is used for the resistor. The main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.
3. The capacitor adopts Germany imported Weimar capacitor to ensure strong and continuous power support.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality
5. The layout of the entire circuit board is quite rigorous and reasonable. The overall PCB trace is grounded at one point. The power amplifier board works stably and reliably, and the output power is large; the sound is beautiful and round, and the sound field is wide. The stereoscopic effect is strong, the low frequency is solid and solid, the signal-to-noise ratio is quite excellent, the dynamic range is wide, the details are clear, the transient response is excellent, and all kinds of music are played freely, and it has a very good performance in the family's playback environment.
6. This board is very easy to connect. It can be assembled into a beautiful stereo HIFI combined power amplifier with very few components, which is very suitable for audio enthusiasts. You can also enjoy the DIY process by changing your understanding of the circuit to more suitable and better parts. (Absolutely worth a try, the effect is very good)

Note:
The heat sink of each board should be more than 6kg
The contact surface between the plate heat sink and the external heat sink must be coated with a layer of thermal grease, the thinner the better under uniform conditions.
Install the screws to tighten
