Each resistor measures approximately 12 mm in body length and 5 mm in body diameter. These 3.6k-ohm, 1-watt carbon film resistors with a 10% tolerance provide a stable replacement component for original resistors found in vintage vacuum tube radios from manufacturers such as Philco, RCA, and Zenith. Carbon film construction offers reliable performance, serving as an effective alternative to aging carbon composition parts while fitting standard chassis layouts, Pkg of 5.
