This PCB is designed for building a stereo audio amplifier with onboard rectification and filtering support. It allows direct transformer connection and provides the base platform for assembling a high-power audio amplifier. Final performance depends on components used and assembly quality.
Output Power
Stereo output: up to 100 W per channel (based on supply voltage, load, and heat dissipation)
Working Voltage
Dual supply derived from onboard rectifier section
Recommended transformer: 24-0-24 VAC, 5 A to 8 A (step-down)
Speaker Compatibility
Supports 4 Ω speaker loads for higher output power
Suitable for stereo audio applications
Performance
Total Harmonic Distortion (THD + N): less than 0.1% at full output
Power Supply Provision
Provision for full-wave bridge rectifier
Supports filter capacitors for DC smoothing
Transformer can be connected directly to the PCB
Construction
Designed for through-hole components
No SMD components required
Components are commonly available
Configuration
Bare PCB (components not included)
Requires assembly, component selection, and proper heat sinking
