Here we have a super quality LM3886 based mono power amplifier by KMTech Design. This listing is for the bare PCB with no components included. Perfect for use with our active crossover filter boards! This is v1.4 of the board, with an RCA connector for the input signal as well as a terminal block. The board was designed in the UK. We also sell this amp as a PCB only. Check out our store. These amplifiers are truly amazing, capable of delivering up to 68W, with extremely low THD and sporting many advanced features such as under/over voltage & thermal protection etc. There's provision for a 0.1 ohm resistor for connecting boards in parallel. Size: W 70mm H 35mm. To finish this amp you will need: 1x LM3886 amplifier IC. 1x 1uF metallised polyester capacitor. 3x 100uF 50V electrolytic capacitor. 1x 22uF 50V electrolytic capacitor. 3x 22k 1% metal film resistor. 2x 1k 1% metal film resistor. 1x 3-way 5mm terminal block. 1x 2-way 5mm terminal block. 1x PCB mount RCA connector (white or black colour). You will need to attach a heat sink as the LM3886 is a powerful chip and dissipates a lot of heat. You will also need a way of powering the amp up. Check our store we have a dual voltage power supply board that is perfect for the job.. IMPORTANT - INSTALLATION BY QUALIFIED PERSONS ONLY AS MAINS ELECTRICITY IS INVOLVED. Thanks for looking! Please note this listing is for a PCB with no components. The listing photos showing the kit and fully assembled unit are for illustration only.
