For over 30 years, is a very old technology, but only initially. Equipment when the voice is not that bad.
This circuit will be forgotten …. Power rear. Many of you may be familiar with it, I put a little adaptation.
Enter Hexfet IRF640 200volts 18amps total price is $ 50 per pair, both computer (the one with no more than 120 kb).
Not suitable for people who like high watt bass heavy or not … because I do not like the sound of that …
But a number of new equipment. Fate of the current can be very high. And of the same type. When this cycle is completed. You will be amazed at the tone.

60W Power Amplifier MOSFET OTL circuit
It’s not hard to create. The device can be adjusted VR100k get half of the power supply (do not just put the FET). Continued…

Come back again ,today i have the simple sound circuit for siren with two tone ,We are going to take the NE555 the various IC of electronic world.

Siren twon Tone Circuit
The Siren two tone circuit is a very simple device but it is also an excellent exercise for beginners because it is very easy to conclude and boosts morale for many projects to come.
It consists of very few parts, and also can be put together on a breadboard (proto-plate). This particular horn using two NE555 timer-wheel which can be replaced with a dual NE556 timer. This siren is also called “Kojak siren”, and is powered from the 12V source. Continued…

Happy new year everyone ,We hope you have a safe and your healthy and happy in 2013.
We’re back in action after a great holiday. For first article for new year,We would like to present the power amplifier circuit for your home audio system or sub woofer for your car .

600w RMS Power Amplifier Circuit
The circuit provides power in 600 watts with MOFETs ,Regarding the project ,We have both schematic and PCB for Audio amplifer and power supply circuit. Continued…
