AB15 Professional Mono Power Amplifier Board - 1500W, Dual DC ±75V, High-Power Audio Transistors

Hey audio builders, check out this AB15 mono power amplifier board if you need serious power. It’s rated for a solid 1500W output and runs on a dual DC power supply of +75V-0--75V. Inside, it’s packed with quality components: 12 pairs of those reliable TT1943/5200 high-power audio transistors, a 10uF coupling capacitor, Taiwan-made main electrolytic capacitors, and 1% tolerance five-ring metal film resistors for a clean signal. The PCB is a sturdy 1.6mm thick double-sided board with 2.0A copper and full tinning, so it handles big currents without breaking a sweat. To keep things cool, it has a high thermal conductivity aluminum heatsink. It weighs about 1.6kg and needs a single AC 12V or 15V (1-2A) supply for the auxiliary circuit. Important note: don't connect pins 1 and 2 of the potentiometer. Perfect for building a powerful mono amp for a subwoofer or PA system. Make sure your power supply and wiring can handle the specs!
