Hi guys,
I was looking to make my own O2 amp since its a lot cheaper than buying premade. Looking at the BOM here:
https://docs.google.com/file/d/0B52Awjeyc5zKYWViZjlhNzItZDBmYi00YjA4LTk1NzgtZTMwNTAzMWQ3Y2Iy/edit?hl=en_US
It seems that the first section includes all the parts needed and comes to ~$27 on mouser, and the PCB is $6 on JDSlabs. Those parts + a power adapter (or batteries) is the only thing I need to getting it up and running correct?
The only thing that's confusing is the section called "gain resistors". Do I need any of those to make the amp? I don't think they show up in the documentation on building it.
