FIELD: electrical engineering.
SUBSTANCE: core of proposed coil that can be used in radio receiver preselectors where tuning frequencies are selected by means of set of adjustable capacitors has toroidal cores abutting against one another which are provided with radially directed and aligned grooves for passing last turn of coil wound on both toroidal cores, if necessary.
EFFECT: enhanced precision of coil manufacture.
