system. The amp is kinda cheap and I think the transformer dosen't supply enough power for the output stage. The Filter caps in the power supply are 10,000 uf I was wondering if increasing the value to 20,000 or 30,000 uf would help with the sound quality, and decrease the strain on the transformer.

This power supply project can supply power to any one channel audio power amplifier project presented in this website. The AC line votage goes into the primary of the power transformer through a fuse and a switch. The AC is then transferred to the secondary winding by magnetic induction to whatever voltage your audio amplifier requires. The AC in the secondary winding …

This application note covers the design of a ±72-V unregulated power supply specifically for audio amplifiers. The power supply is an unregulated design with an option to allow connection to either 120-V or 240-V mains. The design uses toroidal transformers, a fully integrated bridge, and various rail capacitors for
