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.
Old pic (from ebay, no picture taken from my original).
The new inside.
The new front panel.
Standby mode.
