Audiophile Amplifier LM1875 Paralel
In this project I am interested in designing an amp with LM1875 chip-amp with audio grade components to make it produces great sound.
This amp uses two chip LM1875/Mono with parallel sistem on the output (4 chip-amp for stereo).
The special things on this design is :
- Capacitance multiplier PSU sistem included on this single board so you can minimize the wire for installation.
- Included pre-amplifier section and you can use any of your op-amp for this board
- Free space for audio grade capacitor
- Star gounding that makes very very low noise
This circuit requires 18V-0-18V Transformer at least 3A or more
So, what does it sounds like? please check the video on Barlex Respectaizer Youtube Channel
