How to Modify a 150 Watt OCL Power Amplifier - Technician knowledge of electronic equipment, for example, is not owned by everyone, not everyone knows and can solve problems that exist on television, such as television does not operate properly, the screen experiences the problem is that it does not produce an image, there can be problems in the audio part, namely the image appears but the sound does not come out until other problems that are quite difficult to reach, including the problem of the amplifier.
Previously, we will learn about what an amplifier is. Amplifier itself can be called an amplifier, is a series of electronic components that can be used to be able to strengthen power or power in general. The power amplifier can also be said to be the final amplifier of a part of the sound system which later functions to strengthen the audio signal which is basically an amplifier of the voltage and current of the audio signal, the goal is to drive the loudspeaker or what is known as a loud speaker.
Another definition of power amplifier is the final amplifier component so that it is no longer equipped with a tone control, while the amplifier itself consists of a tone control and a power amplifier.
In this case, the power amplifier is tasked with being able to push the preamp-processed signal to be forwarded to the speaker section, generally known amplifiers are 30, 40, 50, 90, 100, 120, 200, 300 watts and so on. This figure represents the driving force that power possesses, but it is not pure.
There are many types of Power Amplifier on the market and ready to be sold, consisting of many types, brands and forms of different Power Amplifier. Such as the OCL Power Amplifier, BTL Power Amplifier, Stereo Power Amplifier and there is also a Mono Power Amplifier. Then, for this type of Power Amplifier, it can be divided into the audio quality or sound which is deliberately made with a standard class.
But in this article, we will give you a way to make modifications to the 150 Watt OCL amplifier which is quite commonly used by many electronic media devices. This kind of activity in general is often carried out by electronic technicians to get increasingly stable audio quality when they find things that are not satisfied with the amplifier they have.
The 150 Watt OCL Amplifier can indeed be modified, usually the modifications made are for the field sound by replacing some of the existing components so that it can be supplied with more than 54 VCT or High Voltage, which aims to get a better bass sound.
Previously, there are several components that need to be prepared before you make modifications as follows:
Elco 22uf 50V 6 pieces
Elco 10uf 50V 2 pieces
2 pieces capacitor 220n
2 pieces of capacitor 10n
After all the ingredients have been prepared, the next step is to modify the 150 Watt OCL Power so that it can produce a round, clear, clean and loud sound and high quality bass. To modify it, there are several components that you need to replace, for more details, consider the following steps:
1. Changed the 3 existing elco to 22uf 50V, previously for the original amplifier using 47uf 50V, the replaced elvo consisted of six pieces, changing the corners of the power OCL, while at the bottom center it was not for 22uf 50V.
2. Replace the elco that is located below the middle with 10uf 50V, where the original is 47uf 50V, there are two channels on the Left and Right channels.
3. Put the green capacitor 100n, replace it with 22n (223J100V), there are two loud basses that are quite solid and sound like a single organ sound on a big stage, replace them with 220n (224J100V).
4. Next on the resistor, input 100K parallel to the 10n capacitor (103J100V), solder to the back. Next, on the Power Supply section, Elco is at least 2 x 4700uf / 80V.
Now that's a short way that you can use to modify the OCL 150 Watt power amplifier, isn't it easy? Hopefully you can use the method above to modify the power amplifier yourself.
