The amplifier circuit output is 3 watts in tube Class A with the 6BX7 tubes used to draw. The project has a normal gain entry to the regular “Fender-like set of” full-range control, treble, bass, midrange and volume. It is also possible for extra high gain jack, the second phase of the tunnel and its own gain control. [...]

One of the things you may not think about when buying a new laptop is what will happen if you lose your laptop AC adapters. Sure this does not seem like something you would lose, but it is very easy to misplace. So it is always a good idea to know where to buy another [...]
Detects if a device is not properly connected to its supplySuitable for battery chargers, portable appliance supplies etc. The above circuit can be useful to detect if the load of any battery charger or plug-in adapter supply is not properly connected. The load can be a set of batteries to be charged or any other [...]
Small in size! Big in use Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The resistor R1,R2 and capacitor C1 provides necessary current limiting. The circuit [...]
800W audio amplifier circuit The audio power amplifier ideal for home user or PA work or for use as a general-purpose subwoofer or hi-fi amplifier. There are many people like to prefer MOSFET as their legendary ruggedness. This circuit project had the Mosfet amplifier module which produced 800 Watt into 4 Ohm speaker load and so we decided to take a look it. It was turned [...]
