Friends, just don't use Cyanoacrylate based ( fevi-quick ) adhesive.
It's vapour or contact can make nearby metal catch very bad rust, oxide... ( including varnished wires )
Here too using hot melt glue, but in the process just don't overheat ferrite cores.
It's better ring-mixer toroid comes pre-assembled,
otherwise I know many kits end-up in corner of junk room, due to lack of knowledge by non-electronic new-bees...
