12 Volt 2N3055 Transistor Amplifier Circuit Diagram

For decades, this circuit has stood out as one of the most impressive designs, with sound quality that is hard to match. Despite being over 40 years old, it still holds its own compared to other circuits.

The output power of this amplifier is an impressive 30 watts RMS, using all transistors. However, I often recommend this project to those who want to build their first integrated power amplifier circuit, and it's especially suitable for beginners.

One of the reasons why I like this project is that it uses ICs, which make it convenient and modern. Additionally, we will be using a PCB (Printed Circuit Board) list below! This amplifier circuit has been popular forever, and it's very easy to find and use.

Although it may seem ancient with transistors, the 2N3055 power amplifier circuit still has classic sound quality that is hard to match. We like this circuit because of its durability and ability to not lose loudspeaker gain easily.

Another advantage of this circuit is its adjustable output sound, which includes features such as Volume, Bass, Treble, Mid Range, etc. It's also an OTL (Output Transformer Less) type, making it easy to build, economical, and durable.

In addition, the 36V power supply circuit for 35 watts to 50 watts amplifier circuit is included in this project. The PCB layout of 35 watts to 45 watts amplifier using 2N3055 transistor is also available.

This circuit is suitable for those who want to build a power amplifier circuit, especially novices who are new to electronics. With its simple design and adjustable output sound, it's a great choice for anyone looking to create their own amplifier.

Components:

* T1: Transformer Secondary for 40 volts 3A-5A

* C1-C4: Electrolytic Capacitors (10,000uF 63V)

* 2N3055 transistors (x3)

I hope you find this article helpful in building your own 12 volt 2N3055 transistor amplifier circuit. With its impressive sound quality and easy-to-follow instructions, it's a great project for anyone looking to get started with electronics.
