Circuit Project Electronic

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.
