"I can't understand why mini resonant transformers aren't used more in
RF amplifiers and filters etc.  Would they have a place in highly
sensitive measurement equipment?"

	They ARE used almost universally where any selectivity is desired.  The
simplest two-resonator "IF transformer" operates on exactly the same
resonant principles as a TC and is most common, but much more elaborate
filters are also used.
