Tubby Amp Kit

This bare bones kit provides everything you need to build your own Tubby Amp, excluding the enclosure, giving you the freedom to build it into whatever case you choose.

Tubby Amp – This kit is a compact, battery powered, mono speaker/amplifier combo. The whole kit including a 9v battery (not supplied) is small enough to fit into an 8oz tub. The Tubby works well as a speaker for the Posc, it can also be used with an mp3 player or a computer, or if used with a pre amp – a guitar. The two inch Mylar speaker offers good quality sound, is stronger than a regular paper speaker and is resistant to rain and water. Download a PDF of the instructions and schematic here.
