Muti lab power supply 15V,30V,45V,60V

Friends ever meet a problem experience Electronics Circuit at want the level Voltage various? I like to make any circuits form old electronic parts,Because it is very cheap, and a great challenge. Today I begs for to suggest Muti lab power supply 15V,30V,45V,60V Circuit may meet the requirement of friends get. By it is the circuit is simple use the transistor = 4 pcs (C1061,A761,Driver 2N3053,2N4037) only and We use a Zener diode 30V (2pcs) has a constant voltage level. The transistor have equiv number many the number. but however this circuit inappropriate for you who want current tall. Because it gives current 0.5A only just. This circuit idea friends, may apply the work has please yes.

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.

Dual linear regulator +15V -15V by Transistor Only

When friends want Dual Regulator +15V GND -15V. Usual like to to use the integrated circuit LM7815 and LM7915. But sometimes seek the integrated circuit no will do ? Today I leads old circuit , but be worthy give friends. Try out the one choice use the transistor and Zener Diode 15V can use be Dual Regulator +15V GND -15V get also. Although complicated more but economize and seek easy equipment certainly. For equipment other list friends can seek pay back can. such as Q1 2N4053 use the number BD140 can replace Q2 – 2N3446 use the number BD139 can replace. Seek buy easy and the price is inexpensive. Request friends have fun Dual linear regulator +15V -15V Circuit , please yes.
