Great work, and quick thinking in using a “jumper” wire to connect the negative leg of that cap to ground. I have a 7$ soldering iron and it is pretty easy to overheat, resulting in a curled up/ peeled off copper trace which ends (the solder pads) become non-existent. I now have a 2-way power bar close by so that I could manually turn off the mains supply when the iron gets too hot. This works pretty well even for soldering SMT components. By the way, if anyone is “mcwillizing” their GG, dun toss away the backlight. Those small CCFLs are fun to play with, you could lit a few sticks up wirelessly with a Tesla coil like what I did below with mine.
