The tone control preamp uses the well-known IC 4558. 2) The second pic shows the soldered portion of the assembled circuit. Heat Sink8. also I actually want to add mire Fets to it because I need a 2000W amplifier unless I could just use the pcb for the first section of the circuit and the place added fets seperate, the circuit which I referred has a recommended PCB with it…actually both the circuits are one and the same, in fact the linked circuit was inspired from the above original circuit from Hitachi. Can PCB be availed by you. Contents: Introduction | Specs | Schematic | Pictures. 12v 400W AUDIO AMPLIFIER CIRCUIT DIAGRAM datasheet, cross reference, circuit and application notes in pdf format. This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Thanks for PCB Mr Swagatam, But i cannot download the image to print it, its part of the website image. . 5) The fifth figure witnesses the speakers which was used for testing the amplifier with astonishing levels of clarity and superb power outputs :p. I used only a couple of mosfets which could generate power outputs well over 100 watts RMS, connecting more numbers in parallel can easily enable this circuit to cross beyond the 1000 watts mark. It is a good practice for the power resistors R18 and R19, to be placed at a distance of at least 5 mm from the circuit board surface. But this has no serious impact on the design, whatsoever.. The circuit below is a simple Push Pull CD4047 Inverter circuit diagram which uses only few components. TR1 and TR2 are the connection for the transformer. Looking at the figure we can understand the circuit with the following points: The involved simplicity would also certainly mean that some of the ideal features of the circuit was sacrificed in the design, for example it lacks a constant current source for the differential amplifier at the input stage of the amplifier. In the circuit uses all direct coupling connection together. Hi Swagatam will this circuit work well with IRF hexfets as well. But what if i leave it untouched? what is the wattage of 100 ohm resistors? Nothing like it is available in its power vs. size rating. I feel that my component rating is not right (may be lower value).so I request you to provide me with the righr resistor,diode and capacitor ratings. helloi just need to get some things straight about the circuit because they're confusing-what is the component right after the input? This 100W OCL power amplifier is excellent sound quality. conversely if the above amp was operated with a 12V then the current required would had to go up to 100/12 = 8 amps, causing a substantial amount of heat generation and involving large heatsinks. can i not do it with amp meter in series with +ve supply ? your own Pins on Pinterest This 100W inverter circuit need power supply : V max: simple 12V DC, I max: 10A 100W Inverter Calibration: Simply power the system and put a frequency counter or oscilloscope at the output of the transformer. Hello Mr. Swagatam, good afternoon. hello, nothing is confusing in the diagram. Yes I am sure, because an amplifier’s frequency range is determined by the devices it uses and the filter networks involved in it. Thank you Andrew, you can find a few driver circuits on this page: https://www.homemade-circuits.com/?s=IR2153. Modifying the power stage of.
