In the following video I showed, how to make a powerful C5200 A1943 Mono Amplifier with jrc4558 ic and heavy bass, treble and volume controllers. The high quality circuit uses minimum components with a low cost and ideal for beginners.
The following video was sponsored by PCBGOGO, a most experienced pcb manufacturer in China. They provide high quality manufacturing of pcb and pcb assemblies. Also they have 24 hours online customer service to handle the engineer’s questions or follow up the orders. Also they provide $50 coupon for new registrant.

List of basic components:
Here are the basic components in the following two images which will be used in the said project. Complete list of components is at the end of this article.
Take one large and thick heat sink for two main transistors C5200 NPN and A1943 PNP for proper heat dissipation. Use mica underneath both both transistors which will prevent them touching with the heat sink. Don’t forget to check continuity with multi meter. It is mandatory because the center pins (collectors) of both the transistors will run opposite voltage which will cause short circuit. Well tighten the transistors with heat sink.
Take two pieces of 0.47 ohms 5 watts resisters and solder each of them with pin-3 (emitters) of each transistors. And them join the other legs of both resisters each other, as shown in the following image.
Now take a small piece of naked wire and solder its both end to pin-1 (base) of both the transistors. Like this way you will connect both base of of both transistor together. Now take JRC458 IC and solder its pin-1 with the naked wire piece as shown.
Take one 100 ohms resister of 2 watts and solder its one leg to pin-8 of JRC4558 IC and the other leg solder with the center pin-2 (collector) of C5200 transistor.
Now take a 10k resister and solder its one leg with pin.8 and the other leg with pin.3 of JRC4558 IC.
Take one piece of small wire and solder its one end with center pin.2 of A1943 transistor and the other end solder with pin.4 of JRC458 IC. Also take one 47uf electrolytic capacitor and solder its positive to pin.3 and negative to pin.4 (GND) of JRC4558 IC.
Now take a 10k resister and solder it with pin.3 and pin.4 of JRC458 IC.
Now take one 10uf electrolytic capacitor and solder its positive leg to pin.2 of JRC4558 IC.
Take one 100k resister and solder its one leg with negative leg of 10uf capacitor and the other leg to pin.4 (GND) of JRC4558 IC.
Use now a 1k resister and solder its one leg with negative leg of 10uf capacitor where 100k resister was joined earlier.
Setting tone controller:
I used here a tone control circuit which I will not explain here. This project is already available at this site. If you want to visit, click this link of Tone Controller for further detail.
Connect and solder the other end of 1k resister with center pin of volume controller of the tone control.
Now take 3.5mm mobile jack and solder its GND of pin.3 GND of volume controller. And other two wires solder with pin.1 of bass controller.
Take one power supply socket and solder its red positive wire to center pin.2 (collector) of C5200 NPN transistor. And also solder the black negative wire with center pin.2 (collector) of A1943 PNP transistor. If you don’t want to use this socket, you can solder the power supply connections directly.
Take two piece of wires for speaker output. Solder one black to center pin.2 of A1943 PNP transistor and the other red solder with the negative leg of 2200uf electrolytic capacitor.
In the below image I am showing the single voltage power supply of 12 volts 1.25 amps, which will be used to drive the said amplifier for demonstration.
Following image shows the amplifier in action. I used two 4 ohms speakers in parallel. If you want to see it live then watch video at top of this article.
