What is your input voltage? 9v? How are you measuring power out?
Yes I would go back to 10T on L513. I haven't built a 9v unit and I
suspect yours is 9v. Likely, the L513 tweaking is probably only for
the 12v version.
I put kapton tape in several places to prevent shorting. Most
importantly on the power jack and left encoder. Also, on the exposed
pins for the power modules. That's about it.
Enjoy the rig!
