Several micro Henry is small enough value - they could be even air-core if you want - it depends on task, construction, current, ets. For that picture (that schematics) - quite often we take large type (2W-5W) resistors (R37, R41), and use them as inductor cores. You can use some online calculator to calc turns number.These are inductors with adjustable inductance. The most common type of variable inductor today is one with a moveable ferrite magnetic core, which can be slid or screwed in or out of the coil. Moving the core farther into the coil increases the permeability, increasing the magnetic field and the inductance.
