100 100w Stereo Audio Power Amplifier Board PCB only

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 PowerStereo output: up to 100 W per channel (based on supply voltage, load, and heat dissipation)Working VoltageDual supply derived from onboard rectifier sectionRecommended transformer: 24-0-24 VAC, 5 A to 8 A (step-down)Speaker CompatibilitySupports 4 Ω speaker loads for higher output powerSuitable for stereo audio applicationsPerformanceTotal Harmonic Distortion (THD N): less than 0.1% at full outputPower Supply ProvisionProvision for full-wave bridge rectifierSupports filter capacitors for DC smoothingTransformer can be connected directly to the PCBConstructionDesigned for through-hole componentsNo SMD components requiredComponents are commonly availableConfigurationBare PCB (components not included)Requires assembly, component selection, and proper heat sinkingIntended UseStereo audio amplifier constructionAmplified speaker systems and DIY audio projectsIntegration into custom audio enclosures
