UHF Substrate tuner potentiometer

摘要

A potentiometer assembly for providing DC voltages for tuning the UHF channels of a varactor diode television tuner comprises a housing divided into a plurality of elongated compartments, each having a resistive element associated therewith. Each compartment is configured for slidably maintaining a replaceable contact-carrying carriage member disposed for engaging one of the resistive elements. A threaded shaft is removably associated with and longitudinally disposed within each of the compartments and is operable for driving a carriage member within its compartment to displace its associated contact member along the corresponding resistive element.
