Here we have a great quality double-sided PCB and all components with which you can build a super quality LM3886 based mono power amplifier.
The board is fully marked out for all resistor/capacitor values etc.
Perfect for use with our active crossover filter boards!
This is v1.1 of the board, with provision for an RCA connector for the input signal instead of a terminal block.
The board was designed in the UK.
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 protection, thermal protection etc.
There's provision for a 0.1 ohm resistor for connecting boards in parallel.
Size: W 70mm H 35mm.
What you get:
1x High quality circuit board, designed in the UK.
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.
2x 2-way 5mm terminal block.
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 other listings we can help you with that.
You will need access to a soldering iron and moderate soldering skills.
Here's all the LM3886 data you need on Texas Instrument's website.
IMPORTANT - INSTALLATION BY QUALIFIED PERSONS ONLY AS MAINS ELECTRICITY IS INVOLVED.
