My brother Hasan is an old project of two channels 300w and 500w versions. Pre-shared 500W 250W Hi-Fi Transistor Amplifier Circuits and SG3525 EI33 ATX 200-600w DC-DC Converter for auto amplifier projects Output power transistors of the Amplifier Circuits 2SC5200, 2SA1943 DC DC converter floor SG3525 pwm control integration is used. EI33 transformers are used…
This is a very good amplifier suitable for driving compact speakers or bass or midrange PA systems. The great advantage of this connection is, on the one hand, the use of commonly available components, reasonable price and also the integration of all basic protections directly on the amplifier board, which significantly simplifies the construction of…

Operating voltage installed on circuit OPA2134 opamp symmetrical + -15v dc Headphone Amplifier Main Features High performance – very low noise and distortion Can be used with high and low impedance headphones High output power (200mW; up to 8Ω and…
Since TO − 204 sheath power transistors are used, cooler, pcb assembly etc. a challenging but high quality design. The amplifier has Output short-circuit protection. T22 and T23 take current measurements over 0.47-ohm resistor and take the T11 and T12 to the cut and go to protection. You can increase the protection sensitivity by reducing…
Despite the apparent simplicity, this amplifier showed excellent quality parameters, which allows you to safely rank it as a Hi-Fi equipment. The amplifier has a very pleasant sound in the mid-eighties was patented. Since then, the element base has changed quite a lot and it has been possible to simplify the circuit, preserving the idea…
HI-FI 2 x 80W Power Amplifier on STK442-090 Micro assembly Most radio amateurs can be divided into two categories: supporters and opponents of microcircuit amplifiers. As arguments for using such amplifiers, the former cite the simplicity of the circuit, high reliability and stability of operation due to the high integration of the microcircuit. As a…
