A variable 1.2 to 19 volt 5/10 amp power supply.

This project consists of a variable 1.3 to 20 volt power supply at a medium current of 5 or 10 Amps depending on the transformer connections. It contains a low cost 3 terminal regulator with a PNP series pass current boost transistor.

Details of the project are contained in the PDF link here.

A simple 5 amp dual power supply.

A 50W dummy load with power level indicator.

This project consists of a 50W dummy load and power level indicator. It makes use of a 50W tubular carbon resistor dummy load purchased at a radio swap meet ex commercial 2 way radio service.
