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…
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…
Darlington Transistor TIP147 TIP142 Amplifier Circuit – Output power @ 4 ohm: 100 W; – Output power @ 8 ohms: 70 W; – Distortion (THD @ 1 kHz / 10 W): 0.02%; – S / N ratio: 115 dB; – Bandwidth: 3 Hz ÷ 200 kHz; – Sensitivity: 600 mVeff; – Supply voltage: 2×30 Vac;…
Amplifier solid Kenwood KAC-718 model subwoofer filter, DC DC converter, Fan control circuit uPC1237HA protection, circuits are taken from Kenwood KAC-716 model. Technical Specifications of Car Amplifier: Maximum Power Output (at 4Ω, 100Hz) 1x 240W Nominal Power Output (4Ω) (0.08% THD at 100Hz, Supply 14.4 volts). 120W Nominal Power Output (2Ω) (0.8% THD at 100Hz,…
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…
The output transistors MJL21194 are of great power and performance. They must be very well adjusted with through screws, washers and nuts and properly insulated from the heatsink with mica insulators. Remember to use silicone grease and tighten the screws very well, so that the heat is transmitted from the transistors to the heatsink. After…
Previously shared RMS 250W auto amplifier JBL filter SMPS EI35 SG3525 project is similar to the PCB design is a very regular auto amplifier circuit. You can use 2x100w rms stereo or 200w rms mono, which can be controlled by bridge connection as well as bass control with cross over circuit with adjustable TL072P op…
The edited versions of the Holy Holton AVXXX series amplifier circuits are of high quality PCB designs. The power transistors of the 400W Amplifier circuit are BJT 2SC5200, 2SA1943, or Mosfet IRFP240, IRFP9240 can be used for this and will change materials for use. Supply voltage symmetrical + -80V DC pcb, schematic, material list etc.…
