This is a 2.5-watt single-channel audio power amplifier kit. It includes the very popular LM380 audio power amplifier, 14-Pin IC rated at 2.5 Watts. It includes a panel-mount volume control so that the device can be mounted in an enclosure.

This amp kit has been designed so that there are 3 different styles of input connectors and 2 different styles of output connectors to choose from. For example, you may choose a 1/4″ Phono input and a 2-pins screw terminal output. Or you may choose a 2-pins screw terminal for the input and an RCA jack for the output. This gives you great flexibility.

It was designed to fit in several popular enclosures, such as the PAC TEC FXT-4624 or the Hammond 1598BSGY.

The gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage. The output power is rated for 2.5 Watts with a THD of 0.2%.

The PCB is 1.2″ long x 3.0″ wide made of .062″ FR-4 epoxy glass. All holes are plated through. The traces are wide to withstand numerous circuit changes.

This kit was designed for mobile (+12v) applications and can be used anywhere that you want a loud sound. You can actually put it inside of your speaker box. Place several of these amps all over your vehicle for special sounds. It comes with an external input volume control.

It is offered with a “Built & Tested” option for those that do not want to build it themselves.
