Read this information carefully! Many mistakes are made with the power supply, causing the amplifier to hum. Once the mistakes are made, it is often impossible to localize them in the power supply, and you'll be looking everywhere at the wrong place, and not find where the hum really comes from. This information applies also when you use silicon diodes. Don't think you know it all. Many sins and mistakes in power supply design are made in professional products. So don't just rebuild'something'. DIY often pay more attention to the power supply, and have better results. Still take some time and read ALL OF THIS before you design your power supply. It pays off to have a well build and correct designed power supply, and the most quiet sound can result only from this. |
