I put a no name 20" flat face throw away set I received as a gift in my den/workshop. After a couple of months the horizontal frequency whistle gets so bad I have to turn it off. Other times if I put a flat blade screwdriver under the front right corner and twist the chassis it almost stops. Probably a flyback with loose laminations. I am sure it will last thirty years like my Zenith. Or maybe 30 days. I use it mostly for background noise when working on the bench or computer.
