Power Amplifier SOCL506 Driver PCB Layout

This SOCL 506 power amplifier has been tested to be very reliable to be used as a field sound system or also a power amplifier that is intended for the room because its character is flat at all frequencies and is very easy to set.

This SOCL 506 power amplifier has a very good performance and also has decent power to compensate for some sound systems with high prices, it can be several times, this can save you budget for DIY'ers who want to have a reliable power but it's quite affordable, you can make the Amplifier SOCL 506 PCB Layout. In the picture below, the PCB has also been provided in the form of a PDF file so that friends can directly print it according to size.

Power Amplifier SOCL506 Driver PCB Layout
This Power Amplifier circuit can be supplied with a symmetrical voltage up to 90VDC, and can be added to the final transistor in order to control large power up to 1200W RMS. You can use a final transistor such as Toshiba 2SC5200 / 2SA1943 or NJW, or another with a large transistor.

SMPS FULLBRIDGE PFC 4kVA Schematic + PCB Layout PDF

Hello DIY'ers,  I will share the schematic and PCB layout for Fullbridge with PFC (Power Factor Correction) Switching Mode Power Supply. I will not explain in more detail this SMPS, you can immediately try this SMPS with PCB Layout below. This SMPS can be supplied with varying input voltages, ie between AC voltages between 90 - 265V, SMPS is still able to provide a stable output voltage. But also need to be considered the components used must be good, and the transformer must be in accordance with a calculation such as a schematic, how to roll the transformer must also be good and tight. Symmetrical 90V DC output voltage.

1000W Power Amplifier Class H Kencleng Pro

1000W Power Amplifier Class H Kencleng Pro, This is a power amplifier with class H topology, see more about what class H amplifier is here:
And this time I will share Gerber files for this class H amplifier, this power amplifier is very powerful, very suitable for use in the field. With a maximum power of up to 1000W on a 4 Ohm load, amplifiers are indeed intended for large sound systems. Besides having a large enough power this amplifier also has good sound quality, can be used for woofers, subwoofers or midrange speakers. The recommended power supply for MV is 70V and HV 140V DC, with a minimum current of 20A.

The following is a Gerber file viewer image, with a double side layout. You can download the Gerber file at the end of the post.

TDA7294 subwoofer amplifier PCB layout

TDA7294 subwoofer amplifier circuit
The TDA7294 power amplifier is intended for the use of subwoofer speakers because the amplifier with the TDA7294 chip is equipped with a subwoofer preamp, there are also frequency and phase settings so we can add or reduce the output frequency as we wish, and for the phase, we can set from 0-180 level.

For frequencies, we can set low tone cuts starting from 100Hz-500Hz on the middle potentiometer. The Preamp Subwoofer IC uses two TL074 and one single opamp NE5532 or 4558

This subwoofer power amplifier can you download the Gerber file, with a double layer 10x10cm PCB size, the file is at the end of the post. and for the next, you can order on the site of the PCB manufacturer provider like JLCPCB.
TDA7294 subwoofer amplifier PCB layout


For the power supply, you can use from 12V to 40V symmetrical DC with a current of at least 5A, to get maximum results. This subwoofer amplifier TDA7294 has two outputs so the total power output can be 60W RMS.
