PS Noise Harvester

It can be assumed that audio circuits require a consistent and noise-free power supply to give the highest level of sonic performance. I assume that the original AC supply first needs one (or more??) transformer steps combined with various types of smoothing capacitors to provide initial coarse voltage regulation??? Then after a full-wave rectification step with one of those 4-diode bridge rectifier circuits to convert to a "semi-circular" pulsed DC signal, I assume you need further smoothing capacitors of various types to filter and regulate the signal further to a relatively flat DC before putting this into a voltage regulator. When I did A-level, the voltage regulators that I used were either three or four pin components in the power transistor styled epoxy package. I remember using large capacitance electrolytic capacitors for the main smoothing whilst using low capacitance ceramic/non-electrolytic capacitors for removing voltage peaks from the signal????

Yes , hence the qualified electrician.
