100 watts Audio Amplifier Mono With DMOS IC MOSFET TDA7293

Proper grounding is essential for eliminating hum and ground loops. Connect the ground terminals of J1, P1, C2, C3, and C4 to the same point. Connect C6 to the output ground. An audio amplifier is an electronic device that...

Last year, a low-cost tube stereo headphone amplifier kit from Oatley Electronics (located in New South Wales, Australia) was built and reviewed. This kit gained significant popularity and was sold globally. The headphone amplifier is based on new old...

Sealed lead-acid batteries are commonly used in power electronics applications, including uninterruptible power supplies (UPS), inverters, and emergency lamps. They provide power to the load when utility power is unavailable. Upon restoration of utility power, a charger supplies power...

The 2SC2987 and 2SA1227 transistors are used in the uPC1342V circuit, which is a two-channel high-power amplifier capable of delivering 80W using two tubes in the discharge circuit. This circuit incorporates a multifunction protection feature similar to the PC1237...

The iPod Shuffle has malfunctioned, likely due to a failure in the controller chip for the mini jack, resulting in the inability to detect the charger, PC connection, or headphones. The arc must be kept short to minimize distortions...

Many times we needed to strengthen a small signal in the region of VHF or FM. The preamplifier that we propose offers 20dB in all the region of VHF and it still can reach also their 500MHz. The amplifier...
