This circuit is of an 2x 2,500W RMS stereo amplifier, super-light and without switching-mode power supply. The circuit just shows a channel, and the power supply that it assists to the two channels. The audio circuit should be duplicated, but the power supply assists to the two channels without problems. A special care should be [...]
This circuit consists of two identical intercom units. Each unit contains a power supply, microphone preamplifier, audio amplifier and a Push To Talk (PTT) relay circuit. Only 2 wires are required to connect the units together. Due to the low output impedance of the mic preamp, screened cable is not necessary and ordinary 2 core [...]

I see in the data sheets that the OPA541 can deliever 5A continuous and +-40V on the supply side. subwoofer circuit The OPA549 can deliever 8A, but can only handle +-30V on the supply side. Here you can opa541bm, simply use a link from the period after the defeat on each chip back 1 / [...]
The work of the power supply is the gain of 2N3053 2N3906 and 2N3904 is fixed internally at 2Watts. 2W switch power supply circuit It is to compensate the reduction of output power due to low voltage supply the transistor uses the Bridge-Tied-Load principle (BTL) which can provide an output of around 1.5 to 2 [...]
Ideal to operate 3 to 24V DC existing on-circuit lamps This circuit was designed to provide that continuous light lamps already wired into a circuit, become flashing. Simply insert the circuit between existing lamp and negative supply. Especially suited for car or panel pilot lights, this device can drive lamps up to 10W. Circuit diagram: [...]
Here’s a standard for ATX Power supply connectors dan ATX power supply pinouts. Standard power supplies turn the incoming 110V or 220V AC (Alternating Current) into various DC (Direct Current) voltages suitable for powering the computer’s components. Power supplies are quoted as having a certain power output specified in Watts, a standard power supply would [...]
