Tron Power Brick - What is this part and where fo you get a replacement?

Looks like a cap of some kind? Game was bought off the internet arrived and was working. Then a burning sell and smoke throughout the room. Game still played though. Opened it up to find an oily residue over the power brick. Looks like this part vented from what I can tell. writing is faded and smudged so I don't know what to call it or what to replace it with:

I'm guessing from the schematic that this is a 3.5uf 440v cap? What kind of cap is it, and where would I get one? Why does the game run without it? Is it really necessary?

This is explained in the MCR troubleshooting guide. Rather than having plugs to configure the transformer for high/low voltage conditions, it's designed to generate a constant-voltage despite changes in the line voltage. It's a constant-voltage transformer design.

That 3.5mfd capacitor is connected to a resonance winding. This circuit filters harmonics introduced by the design of the transformer and stores some energy in case the input voltage dips.

Since it's a resonance circuit, installing the wrong part will do a lot more harm than good because your LC circuit would no longer be operating correctly.
 
Minus the oily board that brick is in great shape.

I just finished redoing another.

It has an unused fuse holder (I just wanted to make the plug side even) and I took the courtesy plug off because its dumb. Otherwise.
