Each resistor measures approximately 9 mm in body length and 3 mm in body diameter. These 56k-ohm, 1/2-watt carbon film resistors provide a stable replacement component for original resistors found in voltage divider and grid circuits of vintage vacuum tube radios from manufacturers such as Philco, RCA, and Zenith. Carbon film construction offers reliable performance with a 5% tolerance, serving as an effective alternative to aging carbon composition parts while fitting standard chassis layouts, Pkg of 5.
