Zenith system 3 high pitch noise and muddy audio

[Dreamsbeard]

Hi all!

I recently picked up this 1984 zenith for free and I think it looks great and all, BUT it seems to me that the TV emits a rather loud high pitch noise (you know that noise that all CRT do). Now I read that it might be the flyback transformer getting ready to go bye bye on me, but I wanted to ask here for advice before I get any further.

Also, it might be me or that I'm not used to older tv audio...but It also seems to me that the audio is a bit muddy. Is it a common problem on those sets?

Thank you all!
