I'm thinking the rosin in the multicores may have gone off in some way
because when I tin the tip and then leave it unused for 10 minutes, it
turns brown and uneven on the tip. I'm using brand new tips.

Are they Antex bits? I've noticed some "new" (old stock) tips which I have
are so & soes to "tin". Even the normal "Bib" tip tinner didn't help. Once
tinned they are fine.
