Below is the list of circuit diagrams of mono and stereo amplifiers, bass and treble used in all amplifier project videos of this website. All the headings of each circuit diagram is designed clickable to watch the related project videos. All the circuit diagrams are using transistors and ICs like, c5200, a1943, d718, b688, la4440 etc.
Following is the circuit diagram of C5200 NPN & A1943 PNP transistors amplifier with the combination of TDA2030 IC which is used as pre-amplifier. You can click on the following image, if you want to download this circuit diagram for permanent save on your computer’s disk. Also you can watch video and working of this amplifier after clicking the above title text.
Following is the circuit diagram of power amplifier using C5200 & A1943 transistors.
Following is the circuit diagram of LA4440 mono amplifier of 19 watts with volume, bass and treble.
Following is the schematic of D718 b688 powerful amplifier with volume bass and treble.
Following circuit diagram contains powerful C5200 A1943 amplifier and volume bass treble controllers.
Following is the schematic of dual LA4440 bass stereo amplifier with volume and treble controllers.
Following is a general purpose schematic of stereo volume, bass and treble which can be used with the wide variety of stereo amplifiers.
Following is a general purpose schematic of mono volume, bass and treble which can be used with the wide variety of mono amplifiers.
Following is the schematic of dual D718 transistors stereo amplifier.
Following is the schematic of dual C5200 transistors stereo amplifier. This is a classs-A amplifier for beginners & students. The circuit doesn’t have any pre-amplifier in it. The control also do not work with its full range. It is a very low efficiency amplifier and provides low wattage on 12 volts. I personally do not recommend to build it for professional use. Click over the image to download and click over the title to watch its project video.
Following is the schematic of dual 13003 transistors amplifier. You can easily get these transistors from any scrap CFL bulb. Open its compartment with any sharp flat screw driver and remove the circuit board where you can easily find these two transistors.
Following is the schematic of single 13003 NPN transistor amplifier. This transistor can easily be found from any scrap 25 watts CFL bulb. All the CFL bulbs are having two of them.
Following is the schematic of single C5200 NPN transistor amplifier. The circuit is a class-A amplifier with very low efficiency. It will provide low vattage on 12 volts power supply. The circuit contains no pre-amplifier and the volume controller doesn’t control sound in its full range. But its good to learn for beginners and students with minimum components. I used here two 104 ceramic capacitors with potentiometer which will act as low pass filter.

Following is the schematic of single D718 transistor amplifier. One 0.22 ohms 5 watts load resistor is highly recommended to connect in between collector and the positive supply of 12 volts. Note that this resistor is not shown in circuit diagram and the project video.
