This page contains links to documents and other tools may be useful. The design document archives contains .PDF-files with schematics and circuit descriptions, as well as Orcad PSpice schematic files that you may optionally use to work on the design, and/or simulate its electrical behaviour.

The descriptions so far only contain the actual audio amplifier circuits, but depending on interest and demand, other parts such as power supply and speaker protection circuits may be included as well (i.e. everything needed to build a "complete" amplifier).

Orcad PSpice symbol and model library for components used in the Audio Experiment designs

Comment:      You only need to download this if you intend to use PSpice 
              to work on the design, and/or simulate its behaviour.
