OCL 150 Watt with 2N3055 and MJ2955

By -
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 :

1500W Stereo Power Amplifier Schematic

By -

Circuit Power Amplifier has a power output of up to 1500W RMS power amplifier circuit is often used to power sound systems keperlun for outdor. In the final image can be seen a series of power amplifiers using 10 sets of power transistors for the ending. This power amplifier circuit using a transistor amplifier from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A 1500W power amplifier circuits for this. Supply voltage needed by the power of this amplifier is the optimal working order symmetrical 130VDC (130VDC-130VDC ground). 1500W amplifier circuit below is a picture series of mono, stereo if you want to make it necessary to make two copies of the circuit. For more details can be viewed directly image the following 1500W power amplifier circuit.

TDA2030 complete tone control

At this time I present a series of amplifiers that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat. Schematics Layout PCB PCB design This amplifier is a mono amplifier type, can be modif for guitar amplifiers. If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.
