Ideal little amp. for a phone speaker ( there are many other uses but you can work them out for yourselves) it runs very well on a single Lipo. obviously not very loud but with a 2in speaker in not much more than a cardboard tube a million times better than your phone speaker. Kevs.

The amplifier is very compact, it has a low power consumption and runs off a 5 volt supply very well. It can easily be modified to alter the gain and comes with an on board volume control. The output is powerful for such a small device. It is easy to assemble with basic soldering skills.

Only seems to amplify active signals like phone. Forget passive input like guitars which is what I purchased it for. I guess I'll just knock a Ruby up on a bit of perf board instead. At least I can salvage some of these components for that.

This was my first DIY kit. It was well set out and a good first time kit. (Instructions on icservices) I would highly recommend this for anyone looking to start anything electronics.
