Morphology

rectify + tube

The phrase is a straightforward adjective+noun composition: 'rectifying' (converting AC to DC) modifies 'tube' (an electron device), yielding 'a tube that rectifies'. This is a regular, compositional pattern in English and would be understandable to a B1 learner who knows the constituent meanings, despite the technical subject matter.

Etymology

Rectifying tube comes from early electronics: it was a glass tube with metal parts that acted like a one-way gate for electricity. The word rectifying here means 'to make straight' or 'to make a steady flow', so these tubes turned back-and-forth electricity into a steady, 'one-way' flow — that's why the name means a 'tube that makes electricity flow in one direction'.
