Many thanks, those make sense. I tested the first one in circuit to see if it was a diode and that seems to be correct.

I think the orange components are capacitors (they are taller than the browner ones), but their markings don't seem to hint at the values, some are marked "AA4", which does not seem to correspond to any marking scheme I have been able to find. Any idea if they *are* capacitors and what the values might be?
