Where i can find it
This was pretty straightforward, but in opening the cap one of the tiny soldered wires pulled off the pad. It's so tiny that I don't have much hope of soldering it back. Any other way to reattach it? I put it back together anyways and now the right cup works fine, but the left is dead. I recommend a warning here about the little wires, if nothing else.
