Desktop Amplifier TDA7297 With class A preamp
In this project I am interested in designing an amp with cheap chip-amp TDA7297 and cheap components, but it still produces good sound.
This amp use a TDA7297 chip with an output power of 2x15Watt and use a class A pre-amplifier that I have modified from the JLH design.
This amp is very compact to use, perfect for your desktop monitor speakers or for use anywhere and of course the output of the class A preamp can be used with your favorite headphones.
This circuit requires an adapter 12V power supply starting from 3Amperes
So, what does it sounds like? please check the video on Barlex Respectaizer Youtube channel
