This Common Emitter Explorer Board is an unassembled learning board kit for a beta-independent, common emitter amplifier. The simple circuit that underlies this explorer board is a great first circuit to digest and will prove to be a useful building block within more complex designs later on.
Drop in any BJT transistor and start exploring. Grab your multimeter and probe the test points while adjusting the timpots to explore again and again. You can hope to achieve an intuitive understanding of transistor biasing, gain setting, and a better overall feel for how these components interact to produce a basic (and very useful) audio amplifier.
