Whew, restuffing caps is a huge PITA but I'm almost done, just one two-section filter left.
I encountered a problem with the sound getting into the picture, the louder the volume setting the more the picture would jump and dance, you can see traces of this in the video i posted but it got a whole lot worse!
Turned out to be a leaky four-section can causing the problem, I found a NOS Mallory on eBay that was close enough because I didn't want to try and stuff a 4 part cap
Here's some before and after pics, the caps are cleaner and not covered in wax anymore but they basically look the same.
I like that at first glance it looks original
