I finished building the crack w/ speedball upgrade last weekend. The sound is fanstistic and I have been enjoying the Crack for the past week.
However, today when I turned on the unit and plugged in my headphone, the right side sound is cut out after I insert the my headphone jack.
I turned over the crack, and I see one side of the LEDs on the speedball mainboard does not light up anymore. I checked all my solder joints and nothing is loose.
Did one of the components go bad in the right channel path?

You have a bad solder joint somewhere. If you dig a little here you will find quite a few threads suggesting to wiggle the wires while the amp is running to locate the loose connection.

Posting your voltages will give us a starting point to diagnose what's going on with your amplifier.
I see a long capacitor lead sticking out of terminal 10, if you have any leads like that, cut them off. If they touch things they aren't supposed to, you may damage the amplifier.

OMG, you are right!!! It turns out the wire connecting to L7 came loose! It snapped off when I was wiggling the wires around the speedball board. Now all is back to its fantastic normal operation! Thank you!

I just cut them off while I was troubleshooting the back of the board. Thank you!
