2N3055 UA723 Power Supply Adjustable 0 30V 2A

It is a simple circuit regulated power supply, based on the known UA723, that drive a transistor Q1 [2N3055]. The regulation of voltage, of expense becomes with potentiometer R1 from 0v-30v DC roughly. In order to we achieve 30 V, will should the transformer of supply TR1, it gives all the current that it asks the load, differently the output voltage it will be found in the levels of 26 V roughly. Essential is the use of a good heatsink for transistor Q1, as well as good quality of potentiometer in the place of R1.

2N3055 using ic 5 Volt Linear power supply regulator
This is 5 Volt Linear power supply regulator circuit. It uses electronics part that seek easily have no zener diode , and the integrated circuit use Transistor 2N3055 and other. Which seek easily use diode perform heal voltage be stable. By diode 1N914 number uses 1N4148 number can replace. For Transistor 2N3417 use the number BD139 equiv get. If use Transformer 1-2A circuit be this size give current get about 1 Amp. Friends may don’t be bored with line this circuit. I thinks it may advantage seek part easy and economize good yes.

OCL 150 Watt with 2N3055 and MJ2955
This is OCL 150 W mono audio amplifier circuit , with impedance 8 Ohms. The supply voltage using 25 volt DC with triple voltage + ,- ,ground. see below this circuit :
Buffer amplifier use PNP transistor is A564 / A733 /A1013 and NPN use D400 / D438. Driver Amplifier use NPN transistor is TIP31 / TIP41 / D401, and PNP transistor use TIP32 / TIP42 / B546. For the transistor booster or end , here I use a 2 x 20355 and MJ2955 . This anplifier is recomended to full range speakers. See pcb line and construction audio amplifier below :
