Construction of the first Bluetooth Portable HiFi has started. I am working on the power supply build.
The photos above show the banks of power supply capacitors, one for the positive rail and the other for the negative. They are connected using copper foil to reduce impedance between the two sets. My design uses up as much space inside the cabinet as possible, hence their physical format. The Charge On/Off switch shaft runs between the two banks. It doesn’t look pretty but it’s a good solution electrically. IMBO.
