Crown Jewel OD

The silk screening for capacitor C9 is reversed. Install the cap’s long lead into the round solder pad. Capacitor C6 should be changed from .047uf to .01uf. These are corrected on the v.1.1 PCB.

I did this the other night while trouble shooting the SP2.
It is pretty close to accurate. I may have a few switched around when there were two of the same component in sequence.
