25 Watt @ 3.9 Ohm Flameproof Axial Resistor.
This is a perfect sub for the Hard To Find 4.0 Ohm resistor.
That’s the one used on many of the under playfield mounted lamp resistor boards.
Seen extensively on early 80’s to early late 90’s Williams games.(see photo gallery)
Almost always some have fallen off, due to vibration.
This resistor is critical for your flashlamps to work, as it lowers the solenoid voltage, to a range the lamp can handle.
A questions that comes up from time to time is what does axial or radial leaded mean? This is calling out how the leads comes out of the component.
Axial leaded components will have a lead or multiple leads coming out of each end of the component.
Radial which many people think is the shape of the component is actually calling out that the leads are coming out the same side of the component
