Magnavox FD3030 / Philips 60hz hum

[DrunkenBeard]

So I picked up this Magnavox FD3030 but it has this terrible 60hz hum.

I've gone through and replaced all the caps on the main PSU board but the issue persists.

I found this thread from 2012 with someone having the same challenge but it went dead.

Any help would be appreciated, I just need to be pointed in the right direction I think.
