This component has a body length of approximately 12 mm and a body diameter of 5 mm. This 1.8M ohm carbon film resistor features a 1 watt power rating and at 5% tolerance. It serves as a reliable replacement component for original carbon composition resistors found in vintage vacuum tube radios and audio equipment from manufacturers such as Philco, RCA, and Zenith. Carbon film technology provides improved thermal stability and tighter resistance tolerances compared to aging original parts while maintaining the correct physical footprint for vintage wiring layouts.
