Conceptual Design[]
Functional Description[]
The power supply serves the task of converting the mains alternating current to direct current at suitable voltages for various parts of the amplifier.
Block Diagram and Description[]
The power supply can be broken down into three main parts;
transformation: converting the 240VAC mains to a lower voltage usually via a transformer.
rectification: converting the AC signal DC, in the current design this is implemented by a full wave bridge rectifier.
filtration / regulation: smoothing the output voltage to achieve a signal that is as close as possible to flat DC, currently implemented using a capacitor.
Design Parameters[]
More design parameters will be added further into the design process.

Design Implementation[]
The details of on-going design should be maintained here.
Circuit Diagram and Description[]
The basic principle behind the power supply is to use four diodes arranged as a full-wave bridge rectifier to rectify the AC-mains, and the use a capacitor in parallel with the output to provide smoothing of the output signal.
Further circuitry will most likely be necessary clean the supply further.
