Hello,
I want to present you my latest toy, built from junk parts I had laying around
Basically I was inspired by the Cmoy Amp but optimized the schematic to fit my needs and to work with a LME49720 since the original design oscillates like crazy with it
Since I didn´t use a prof. PCB and used only basic material I had laying around, I needed some extra space for the components to fit.
I didn´t use a potentiometer ( no space available ), used instead a fixed voltage divider to not leave a open input.
In order to start and to shut down the unit, you need to open the lid. I used a micro switch which I shortened the lever
Well, there is nothing more to say, here are the pictures .
I adjusted the gain to a normal level only ( about 2,8x ) since I will only use this unit with my Nexus 5 or Nexus 7 ( 2013 ) for some extra. gain
Best regards,
