An easy to build, powerful, Stabilised power supply with variable output voltage from 2 to 30 volts and a maximum power rating of 5A. It covers almost all of the voltage needs in the electronic laboratory.
Circuit is a tried and tested design that uses an LM317 variable output voltage regulator IC to drive three parallel 2N3055 power transistors.
The kit comes complete with a large pre-drilled heat sink for the power transistors. You need to add a 24Vac/5A mains transformer.
