230Volt LED Circuit
This is a circuit that is used to menhidupkan LED with voltage 230Volt, 230Volt it so that the voltage must be lowered in accordance with the needs of the LED itself. To lower it even necessary circuit as below.
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 : Click to view larger PCB line Components are already installed The booster amplifier already installed.
