My top C key came loose from the key return spring. When I opened it up, I saw that the little nub on the key that holds the spring broke clean off (Looks like there could have been a DIY repair using a juno-1 key return spring, maybe there was too much tension?). The replacement key is out of stock and so are other similar Top C keys that work.
Has anyone had any luck repairing something like this? I’ve tried gluing a tiny bead in the place where the knob was and it ripped clean off right away. Maybe there’s an optimal super glue I should use?
