- R334 is 100k in the 808, and 150k in the Yocto
- R200' doesn't seem to exist.
And finally the one which seems to have been causing all the problems:
- The BA6110s Input bias (3rd pin) doesn't seem to be grounded in the Yocto schematic (infact it doesn't seems to be unconnected in my files), however in the 808 schematic the BA662's 4th pin (appears to be the input bias from this schematic) IS grounded. So I grounded the 4th pin of the BA662 and voila! Seems to be runnning perfectly!


Here's the 808 schematic file I used:

Would this work in the Yocto v2? I have an original BA662. Do you need to jumper R200?

Thanks I’m advance!!
