A complete amplifier module for subwoofer on the TDA7294 bridge. Implemented functions: power amplifier based on TDA7294 (70-140W) gain regulation adjustable low-pass filter (80-150Hz) with the option of shutdown (full-band operation) phase switch (0-180 degrees) subsonic filter (passive 3-order 19,25,33 Hz to choose from) auto-on / off with the switch of this function (ON /…
I also post a car amplifier, 100% own achievement. The amplifier consists of SMPS (switching source), SG3525 oscillator and 4 + 4 N-mos IRFZ48 and the amplifier is according to the “classic” N-mos 350 scheme with 6 IRFP240 endpoints. The transformer for SMPS is made of two smaller transformers recovered from an inverter, of which…
TDA1514 stereo previously had shared 2 × 50 amp circuit, see: TDA1514A high performance HiFi 2X50W amp circuit This circuit can be used for single-channel 50w output printed circuit sizes quite small and symmetrical placement of smooth supply voltage can be between 2 × 10 volts, 30 volts 2x material list diagram, PCB drawings are…
Headphone Amplifier Circuit simply have a design or even the first single MOSFET as the design begins after two MOSFETs used and 6n6p ecc99 lamp Adding the lamp operating voltage 70 … 80V inter-addition for the MOSFETs 18 … 20v voltages required. The second box of the amplifier are also very well designed. Hybrid schemes…
I think there is no one who knows the 200w amplifier circuit, whose power is increased by connecting 2 TDA2030 power transistors to its outputs. I first saw this circuit in the elektor in the 2000s. There was a thin and long PCB printed circuit drawing. It worked very well. Actually, my purpose in making…
Apex B500 power amp’s pcb design stylish been output mje15032 and mje1503 power transistors used supply voltage symmetrical 55v … 90V from quite high dangerous circuit tests, be careful addition amphitheater to be used with fan control and protection circuit diagrams and PCB drawing is on.

Microlab 2 +1 Amplifier circuit used in the 6331 model-amp ICs TDA2030A TDA2030A bass output at the 2 bridges connecting the power is used only integrated for enhanced RL. Bass TL082 op amp filter used on floors. 2x13v 100w transformer used in the circuit. Source cxem.net pcb files: FILE DOWNLOAD LINK LIST (in TXT format):…
The design is very good speaker guitar amplifier dc protection circuit 5 band equalizer amplifier amplifier parts on the floor of the pre has Irfp240 Irfp9240 MOSFETs used. Input amplifier voltage gain and control area +/-7five DB bandwidth can be set. According to the very high performance oscilloscope measurements. The author states that the guitar…
TDA7293, despite the small performance too high an amplifier integrated manufacturers (ST Microelectronics) “120volt 100watt DMOs audio amplifier with mute st-by,” says symmetric +-60V 120-volt dc able to work with TDA7293 datasheet information according to the maximum recommended working voltj the +-50v 60V input audio signal when it is not in the lowest operating voltage…
Always on my mind I would say if you did a nice 2.1 amp circuit .. although oddly fond of side projects on the internet, not a nice mono, stereo amplifier circuit as they do not have in abundance , but 2 +1 … Half- bass is solid at National Semiconductor LM3886 amplifier integrated product…
