So recently my grandparents died and when going through their house there was an old Magnavox console from the early 60's that was going to get thrown away so I took it. It actually worked perfectly after I cleaned up the selectors on the top, but here the other day it stopped working and I am trying to figure out how to repair it. I have a decent amount of experience with electrical stuff however something this old that uses tubes is unfamiliar to me. I recorded this video to show what is going on with it since it's way easier then trying to explain it via text.

Here are some pictures of the console and the sticker with the model number on it
