DIY 300W Stereo Transistor based Amplifier PCB – Without Components

Product Description: DIY 300W Stereo Transistor Based Amplifier PCB – Without Components

The DIY 300W Stereo Transistor Based Amplifier PCB is a high-quality bare PCB designed for audio enthusiasts and electronics hobbyists who want to build their own high-power stereo amplifier. This PCB supports a transistor-based design, providing excellent sound clarity, stability, and power handling. Perfect for custom amplifier projects, it allows users to assemble components according to personal specifications or preferred parts, enabling flexibility and experimentation in audio circuit design.

Features:

• High-power stereo amplifier PCB supporting up to 300W output

• Transistor-based design for superior audio performance

• Bare PCB (without components) for DIY assembly

• Optimized layout for heat dissipation and signal integrity

• Suitable for both novice and experienced electronics enthusiasts

• Compact and durable PCB construction

This circuit is 100% tested.

        So be patient! Take your time to go through the all component which marked on the top of the PCB & check twice with your parts.

**Always use good quality component, and you must really Consider about the voltage of the capacitors (or it may cause to the unwanted noise)

POWER SUPPLY UNIT

PCB input voltage is between 24-30V DC. We recommend you to use 30V, 10A center tap transformer.

PCB hasn’t any built in bridge rectifier. So please use below circuit to power up the circuit from 24-30v AC center tap transformer.

• Transformer is 30Vx2 , 10A (center tap)
• Capacitors are 10,000µF (50V) {if you Hard to find 10000µF it is ok using 6800µF}
• Diodes are IN5402

Applications:

• DIY high-power stereo amplifier projects

• Audio system customization and upgrades

• Electronics hobby projects and experimentation

• Home audio amplification solutions

• Educational electronics and training

Package Included:
1 x DIY 300W Stereo Transistor Based Amplifier PCB – Without Components
