Glad to hear it worked.
But in general I would say watch the heat though.
A lot of the time when you solder, if you are not very careful, you will melt part of the insulation. If you solder directly on the coil, you could melt all of the insulation and fuse the coil into a lump, thus destry
I would recommend unspooling a bit from the coil as you did and solder that to the PCB whenever possible. The wire is too thin to transfer much heat back to the coil.
