A more stable, stable version of the 100 Watt Mono Amplifier known as ZENER in Colombia. It can deliver 100W power with an 8 Ohm speaker and can also be used with a 4 Ohm speaker. Its noise is very low, and it does not make an explosion sound when opened. Even though I use…
Amplifier D-class Music power 500W. (RMS 300W) NE5532, IR2184, KNP9120 mosfets. A simple D-class amplifier, based on a modified version. Protection of the amplifier against a short circuit at the output, clipper Limiter. Class Amplifier Characteristics: RMS power: 300 watt Load resistance 4 ohm Supply voltage +63/-63v DC Frequency range: from 5Hz to 80-180Hz (depending…
Tone controlled stereo amplifier circuit. You can use TDA7377 or TDA7374 amplifier IC. LM1035 or LM1036 IC can be used for tone and volume control. The cooling fan control made using TL081 op amp contributes to the circuit. Has adjustable voltage output with LM317 to power mp3 player or other audio sources.. The LM1035 (LM1036)…
The amplifier gained popularity with its ease of assembly, excellent repeatability and acceptable characteristics, while having a simple circuit, and of course the advantages of class-B (relatively high efficiency and good thermal stability), without the inherent distortions of this class. using the NE5532 operational amplifier, there is no need to introduce a zero offset adjustment…
Transistor 2X100W stereo and mono bass amp circuits by converting 12V battery voltage (between 11v…14.4v) SG3525 DC DC voltage amplifier circuit to around 2X30…35V. There is protection against short-circuiting in both circuits and short-circuiting of the transistors at the amplifier output and giving DC voltage. The 120W subwoofer amplifier has an adjustable bass filter circuit…
The dimensions of the PCB board are 80×80 mm. Each board is equipped with its own protection device that disconnects the load in emergency situation (appearance of constant voltage at the output or breakage of any of secondary windings of the power transformer), as well as performing the necessary load connection delay when power is…
The DIY version of the Crown XLS series professional amplifier is tried and tested and is even sold as a kit. There are 300W, 600W, 800W, 1200w versions that have been applied by removing some parts without changing the design of the original circuit much, I prepared a PCB for the 400W version. Crown XLS…
100W Amplifier circuit provides high power with less material. Output transistors 2 2SC5200 NPN transistors. PNP transistor is not used for output in this amp design. The operating voltage of the 100W Amplifier circuit is 2X46V DC. If you want to operate at higher voltage (max. 2X56V DC), you should use 2SC3858 or similar power…
When I found a regular PCB drawing of a 100W amplifier circuit that I had in mind for a long time, I went into practice. Darlington (TIP147 TIP142) power transistors are used in the circuit output. Ideal for active speaker system or subwoofer, guitar amplifier, home theater systems, instrument amplifier… Clone version of 100W Amplifier…
The single channel 200W version of the amplifier shared in the article 400w (2X200w) Transistor Amplifier Circuit was designed as small as possible in PCB size. The power transistors of the 200W Afi circuit do not require the classic 2SC5200 and 2SA1943 quiescent current adjustment. The amplifier can deliver 100W RMS power with a 4-OHM…
