That's a resistor tied to the flash lamps. Since the color stripes are burnt away, you'll have to look at the playfield schematics.

It appears to be a 330 ohm 2W resistor.

You can use this as a replacement: https://www.greatplainselectronics.com/proddetail.asp?prod=RC7W-330-SQP

It is rated for 7W, which would be much less likely to burn out.

Or.. you could clip one leg and get a couple led flash lamps and be good. If you plan to install leds it needs to be removed anyway.

That resistor supplies a small amount of current all the time to keep the filaments "warm" to make the bulbs last longer. If you use led flashers you have to clip off one leg or remove it because the small amount of current will make the leds glow.

The small diodes you can use 1n4007 for everything. They are 20 for $1.

One thing, when you install your mpu327 make sure the old brackets will not contact any solder pads or traces on the board. There is a thread here of issues where the bracket needed trimming.

If the top of your playfield is as nice as the bottom you got a nice one. The bottom is as clean as a pin.

Resistors don't supply current. Maybe you meant the circuit that resistor is a part of?

The flash lamps are driven by a solenoid transistor on the driver board. So, the purpose of the resistor is to knock down the voltage intended for solenoids to the voltage that flash lamps can handle. As far as I'm aware, there isn't a warming circuit in place there.

ForceFlow the 1 ohm 1/2 watt resistor and the 2 #89 bulbs are the voltage drops in the circuit. The 330 ohm resistor is the warming resistor.
The power is constantly flowing through the bulbs and the warming resistor back to ground. The resistance is high enough to not let the bulbs glow but keeps the filaments warm. When the transistor fires the current goes to the least amount of resistance (1 ohm resistor) and lights the bulbs.

Ok. Let's micro manage words. I believe you knew what I meant. Let's try this instead.

The resistor allows a small amount of current to pass.
