LM1875 Class-AB 30W 120V Ready-to-play

This is a flat Class-AB audio Amplifier. All modules are made using though-hole components only, that are soldered to 3mm traces of single-sided FR-4 PCB. XF-AMPS01 is powered by regulated dual ±DC power supply that is decoupled from main via transformer. This unit features large capacitors, large heat sinks,  and phoenix connectors. Driven by LM1875 USA-made IC this amp is build to last.
