Mini PSU

Mini PSU - simple power supply unit for audio amplifier. Single layer PCB can be easily made at home. PSU have DC protection, delayed ON and fast OFF features build in so there is no additional circuity required for speaker protection. Transformer input voltage must be in range 2x24VAC to 2x35VAC. I have prepared two PCB versions, the smaller one for 25mm diameter main capacitors and the bigger PCB for 35mm ones. Bellow thermotransfer and gerber files (ask for single layer boards).
