Updates...

I was supposed to work some more on this Sunday but She Who Must Be Obeyed decided she wanted to paint the kitchen, so there's that...

The top of C6 capacitor feels like a firm bubble, meaning I can push it down and it springs back up.

The noise is loud enough to hear, especially when turning the unit off. Not sure if you can hear the sustained tone in the video but you can most definitely hear it when it turns off... https://photos.app.goo.gl/HboTvjY7sfEbCBpJ6

Audio signal does *not* pass through.

I'm at the point now where I'd like to ask if anyone wants to try and fix it for me? I have two speakers that work so I can get back to rebuilding my studio now.

I was wondering, though, since all you guys have experience with these speakers, are you audio engineers too?

You can try to pinpoint where the noise comes from, if it is from the new inductor try to put the old one back like I mentioned in a previous post.
