Apology if this is a dumb question but is there any easy way to tell
whether a reluctant-to-strike light needs the tube or starter changed?

It's easy.

If you have a spare starter then it's the tube that is knackered

or

If you have a spare tube then the starter is knackered.

If you have both spare tube and starter then it's almost certain to be due
to something else completely.

Hope this helps
