Here is A amplifier with 2n3055 transistors on its output for those of you that are looking at doing a bang for buck amplifier with all those 2n3055 lieing around that as most electronics guys think when they look in there old box there must be something I can do with this stuff.

This is an easy to make power supply which has stable, clean and regulator 0-28V 6/8 Amp output voltage. By using two 2N3055 transistors we become more then 2 times the amount of amps then the power supply delivers, making it real though to brake ;). Although you could use this design to deliver 20 amps (with almost no modifications and with a proper transformer and a huge heat sink with a fan), I did not needed such much power. Make sure you mount them on a huge heat sink, as the 2N3055 transistors can get very hot at full load.
