The cost is high 🙂 output stage 14 (IRFP240 IRFP9240) Total Supply voltage MOSFETs used quite high +92 V-92V Be Careful The 800 Watt AV amplifier is based on My 1kw Amplifier and shares the same topology and basic PCB layout. The only real difference is the number of Output devices that the unit uses.…
Quality pcb printed circuit design with two amp circuit I share 180 watt amp circuits used in power output transistors 2sa1943 2sc5200 supply voltage + -45 volts DC P-CAD 2001 prepared by the PCB and P-CAD 2001 Schematic prepared by the schema file there. 450 watt amp features the same count in the circuit and…
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…
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:
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…
2200W High cost an amplifier project if you want to go ahead kck87 our friend minding 2200w amp circuit Proteus ares with PCBs have drawn 56 IRFP250 Mosfets used supply voltage is too high (+-150V) Be careful circuit now has not been tested. 2200W amplifier circuit drawing extension’s source has pcb ares proteus .. High…
2 for two different transistor pcb printed circuit crafted case you can use the appropriate Transistor 2N3055 and MJ2955 Used in metal sheath version TIP3055 and the plastic-type metal-sheathed version is more powerful than TIP2955 size and structure, but with better heat transmission cooler installation more difficult. Circuit 8Ω speaker with 50W RMS 4Ω speaker…
Darlington Amplifier Used in the output stage power transistors TIP142 and TIP147 4 can be found in all parts 8Ω 145W 4Ω speaker with market power can give 275W two-channel stereo whether you can use the same circuit two. Anfi circuit total of 100 volts dc supply voltage symmetrical 2x50v Circuit quiescent current adjustment circuit…
