📦 Specifications:
- Maximum Input Voltage: 2.8 VPP
- Gain: 15X
- Input Resistance: 100K ohms
- Output Power: Class A - 15 Watts at 8Ω or Class AB - 20 Watts at 8Ω
- Recommendation: Incorporate a CRC filter post-rectification for optimized performance.
🏆 Assembly Instructions:
- Utilize the plated-through holes for soldering components exclusively from the bottom side of the PCB. Avoid drilling or enlarging holes to maintain the integrity of the through-plating.
- Before assembling, clean the PCB surfaces using isopropyl alcohol or an electronics flux remover to ensure a pristine working area.
- Begin your assembly with the lowest-profile components first, encouraging an orderly and efficient build.
- Accurately position components by verifying their values with a multimeter before soldering, and ensure each part is placed in its correct location on the board.
- After soldering, meticulously clean away any residual flux, inspect all solder connections, and test for potential short circuits using a multimeter.
💍 Tips for Success:
- Prepare an external heatsink to manage thermal performance effectively during operation.
💍 Please note that we only provide schematic insights related to the amplification section of the circuit. If you require a complete set of parameters, you will need to reference the PCB directly.
Enjoy the rewarding experience of building and tuning your own power amplifier with the MOFI - Musical-Fidelity A1 Class A Power Amplifier PCB Project!
