  1. This supply can't give you large current. If you try, for example to sink 500mA, the power on the transistor would be 10W!! This will destroy the transistor! You must change th 2N2222A with BD179 for example. The BD179 can handle 30W, with a heat sink. 'You have a mistake in the schematic. The earth in 230Uin isn't the same with the earth in the circuit. You must remove the first earth, if you want to do simulation.'
