TDA7293 vs TDA7294 Audio Power Amplifier Project

TDA7293 VS TDA7294 Power Amplifier
This is an audio power amplifier project using the TDA7294 and TDA7293 ICs that I will try to work on both. Both ICs are almost the same even very similar scheme can be used in a series of stereos. And in this post, I use one PCB stereo, where on the left side IC using TDA7293 IC and right side using ICTDA7294. Previously I will share the circuit scheme of both IC Power amplifier below with the required components.

Assembling TDA7293 & TDA7294 Power Amplifier [VIDEO]

VIDEO Test TDA7294 TDA7293 with Subwoofer Speaker 12 Inch


VIDEO TEST TDA7294 with 8 Inch 2Ohm Subwoofer Speaker 200Watt

In the video test I use 25V power supply with 10 Amperage  voltage current using Switching Mode Power Supply.
