Description
Conversion old unregulated Tandy power supply to regulated 9 and 5 volt output.
Has also the little Voltage Sensor on board.
A new life for this power supply after 35 years, spending most of it in the attic. Had only a transformer,
capacitor and rectifier bridge. It had a fuse a long time ago ... Mostly all recycled parts with some new in the mix.
