• Notes
• Primary intended for use in auto-coupled tuning circuits where the middle section of the windings is included in the actual aerial circuits, and the detector or H.F.Amplifier is connected across the whole of the windings.
  This arrangement provides for a loose auto-coupling and enables a greater degree of selectivity to be obtained than with ordinary direct coupled circuits.
  This Auto coupler may also be used for many other radio purposes and will be found very suitable for use as a tapped aerial or anode inductance.
  20, 40, and 60 turns being available as required.
