Abstract
An adjustable potentiometer assembly provides tuning voltages for application to a varactor diode tuner in a television receiver. The assembly includes a substrate having distributive resistive elements formed thereon each with a tuning area at which the correct tuning voltage is established. The distributive resistive elements are formed in at least one row with the tuning areas aligned. In addition, the width or tuning range of the tuning areas for each channel are substantially equal.
