Each resistor measures approximately 15 mm in body length and 5 mm in body diameter. These 12M-ohm, 2-watt carbon film resistors provide a stable replacement component for original high-value resistors often found in grid leak or bias 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.
