The kit is supplied with a pre-built jack cable, an 8ohm 66mm speaker, and a AA battery pack and can run off any voltage from 2.2 to 5.5 Volts (Absolute Maximum 6V). For a full list of parts, see the Contents section below.

Previous versions of this amp included a PP3 power connection and were designed to operate around 9V, V3.0 has been designed for use with 2 x AA batteries. There are several advantages to using AA batteries over PP3, they include; AA batteries are much cheaper, more readily available and will also last significantly longer than PP3 batteries, anything up to ten times longer.

Note: this kit requires soldering.
