Amplifier LM4766 integrated circuit made with two channels can give you 40 watts per channel output has supply voltage of 28 volts DC Output section 2 × 0.9 mm wire used in the coil to be wound round of 20 LM4766 Audio Power Amplifier Dual 40-Watt THD+at 1kHz at 2 x 30W continuous average output…
TDA7293 integrated amp I used to reproduce the sound quality is really very clean “td” series about integrated change the negative thoughts I can say that this integrated TDA7293 120v 100w Dmos Audio Amplifier Very high operating voltage range (±50v) Dmos power stage High output power (100w @ thd = 10%, rl = 8w, vs…
1000 watts power quality have a design output stage 6 irfp9240 (P-Channel) and 6 irfp240 (N-Channel) used the audio input section of the lf411 JFET input a quality op-amp opamp onset 15volt zener are provided with amp circuit supply voltage + -40volt and + – 90olt two feed Quiescent current BD140 BD139 transistors oval connected…
System 500W RMS at 4 ohm 620W RMS power gives 2Ω, 4Ω 500W RMS, 8Ω 380W RMS Circuit of the original scheme 8 MOSFETs used and 4Ω 400W writes 2Ω speakers in order to work 10 mosfet I used the original transistors toshiba 2SK1530 and 2SJ201 but the price is expensive to have found IRFP240…
I tested a working amplifier circuit TDA1562Q made with two pieces of the price a little expensive, but the performance is pretty good, stereo want to use Car Amplifier circuit wiring diagram TDA1562Q Note: For the sake of clarity of the drawing next to the socket erased some elements of this transaction was done just…
Opamp and transistor circuits are very nice quality headphone amp design quality for this circuit also has a symmetrical power supply circuit. Design of printed circuit quite well, especially the materials used, the cost comes to almost a high-powered amp, but prices on the name Hi-Fi 🙂 High quality Hi-Fi Headphone Amplifier Circuits all files:
TDA7384 is carried out with a nice amp circuit powered + 2.13 volt single supply 22w power at 4Ω speakers can give TDA7384 and very little material is being established for the project and the amplifier circuit diagram drawing eagle drawing printed circuit there. TDA7384 4 x 35w quad bridge car radio amplifier high output…
Especially Pioneer, Kenwood, Sony, etc.. TDA7240 is used in popular brands like car stereo integrated amplifier powered with a simple amp 12 volt single supply integrated circuit with a power output of 20 watts and two prompts, stereo can use the circuit used. Integrating the output short circuit, over temperature protection there. TDA7240 The TDA7240A…
Very nice design motherboard cpu cooler to cool the MOSFETs used in the most excellent single source of supply + 40 volts is not symmetric Class A Amplifier circuit 30w output power at 4Ω speakers are powered by +40 v supply voltage Mosfets IRFP240 used 4 was prepared with PCB Layout View and Print output…
A beautiful design power and operating voltage pretty high 🙂 detailed explanation (in English) diagrams and PCB files are photos of a top version, but not much change According to the calculations used transformer power 625W output voltage 2x50v total 100v ac Be careful, high voltage Rectifier post dc voltage 70V DC + – 2x70v…
