Many Electronic circuit projects in simple ways of learning

Power Amplifier OCL 100W With MJ802, MJ4502

Today I begs for to advise Main Power Amplifier OCL 100watt by MJ802, MJ4502. May pleasing of friends at like firm bass and Treble be bold. Because it is Amplifier OCL model Class AB. And it has electric tall power about 100Watt at 8ohm size loudspeakers. Then can use in the work party or in the system home theater get comfortablely. Important aspect be power supply Source must have enough about +38V GND -39V that Current do not lower 3 Amp per Chanel. When see the circuit has moderately detail. Then not convenient for a novice for the convenience and friends have model PCB give friends see with. Have a good time with sound of sweet-sounding music , please sir.

  1. 100w OCL amplifier, if someone makes that one, opamp will smoke due to the excessive output current…
    Your R17 value is 1000 times off, 5.6ohms should be at least 5.6Kohms

  2. I want to build the 100 watts Amp, what i plan to do is to connect a zender diod along with a 5.6k resistor so to supply the OP-am IC, will this work well??
    please i look forward to read from you at my email address at (dnkwenti @ gmail . com )
    thanks for your time sir.

  3. OCL 100W amp. If you’re going to rip of Rod Elliot’s work atkeast put a link to his site. Then people could actually see how to build a proper amp and not he bodge you have shown.

    Elliot sound Products original project 3 or P3. P3a is an old advancement on it.
