	Indeed.
	However in this specific case, it appears this inductor
	was used to _regulate_ manually for a fixed value of
	primary voltage, as other parameters were varied.
	In that SPECIFIC context, i suspect 'regulating' coil
	is apt.  If the same coil is were used to trim the
	frequency, then tuning coil seems apt.

	Concur.
