300Watt audio amplifier HIFI by MJ15003-MJ15004 Transistor

Follow the request of friends who likes High power Amplifier Circuit. I then beg for to advise this circuit. It has can to give the electric power about 300Watt RMS unless. Still be amp OCL Model Class AB give sound tall power and certainly should systematically protect that excellent a loudspeaker then torn difficult. Besides still use Transistor replace the integrated circuit then give waste matter feeling cancels bland three goes up and have MJ15003 and MJ15004 then have respond electric good enough power. When friends see the circuit has already , will have plentiful detail,then inappropriate for hobby Electronics man type. But if friends want to try build , have no a problem , be lucky.

300W inverter power 24Vdc to 220Vac by MJ15003,CA3130,CD4027

This is circuit 300W Inverter power,so input battery 24V to Output 220Vac 50Hz 300W.

I used main Component IC CD4027 , NE555,CA3130 and LM7805. The transistor power MJ15003 driver transformer 24V 10A min.
The VR1 – 100K is control Frequency output at 50Hz 50Hz or 60Hz at Square wave signal.

The VR2 – 50K is control voltage output at 220V.
Note:
C6 = 0.1uf metalized-film capacitor, 5% tolerance.
Please read more in image circuit.

Power Amp OCL 100W by Transister MJ15003,MJ15004

This Circuit Power Amp OCL 100W by Transistor.It old circuit,but very well amplifier schematic.
Use transistor MJ15003 and MJ15004, power supply +38V,-38V 3A.
Output power 100W at Speaker 8OHM.
