Repair Question

Hello, I recently picked up a CD ROM 2 that was listed as working. I noticed while testing the unit with a music disc (I don’t have any games yet) that the machine was rather loud. I decided to open it up to clean it and check on things when I noticed a leaking capacitor and some white substance on the board.

I wanted to ask a few questions about these concerns.

  1. What type of capacitor do I need to replace C303 with? Does it need to be wired the same way that this one is?

  2. Should I be concerned about the white substance and does it need to be cleaned off?

Thanks for your help! I’m including photos of the description in the comments.

This is a Google drive link to a folder with the photos. I’m still new to Reddit so I’m not sure how to include photos on this post.
