5V lab power supply

Friends at like to experience is digital circuit has evered to get into trouble have no 5V lab power supply ? In time wants emergency. but seek buy the integrated circuit can not. We come to try use the transistor be 5v voltage regulator circuit better. A friend who have old equipment may sure lollipop. The all equipment can seek to replace can is finished such as Transistor 2SC1061 replace get many the number TIP41,MJE3055 or the other. Zener Diode use 9V 0.5W sizes or 1W all right. For transformer use 6V sizes or 9V 1A only. You get 5V lab power supply that give Current get about 1A already please sir.
