Today I seeks variable power supply circuit come to deposit again. Which be the circuit that use base equipment, build not difficult follow the circuit can fine volt get 0-30V , give current get about 1-2A depend on transformer at you choose to use. The prominent point of the circuit use transistor join a pin [...]
