C5200 A1943 JRC4558 amplifier DIY homemade

The C5200 A1943 JRC4558 amplifier with tone control is a popular DIY homemade project for audio enthusiasts. It combines the power and efficiency of the C5200 and A1943 transistors with the superior sound quality of the JRC4558 operational amplifier. This amplifier provides a clean and powerful audio output while offering the flexibility of tone control for an enhanced listening experience. Building this amplifier from scratch allows individuals to customize the design and components to suit their preferences.

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 (tone control). The high quality circuit uses minimum components with a low cost and ideal for beginners and students.

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 provided above in the ‘Components List‘ section of this article.

Installing components:

Take one large and thick heat sink for two main transistors C5200 NPN and A1943 PNP for proper heat dissipation. Use mica underneath the both transistors which will prevent them touching with the heat sink. Don’t forget to check the continuity with multi meter from collector to heat sink. 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 then join the other legs of both resisters each other, as shown in the following image.

Soldering components:

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.
