Vintage Synth Repair

Sounds like you can do it. I'd just heat the existing solder to get it
to rebond. If it cracks again down the road it might be a good idea to
de-solder, get rid of any rosin, and then resolder the prongs. I need to
find time to do the same thing to my electric shaver over X-mas break :)
