Or are you experiencing a low frequency hum in the audio circuit? That can usually be fixed, unlike the 15.734 kHz whine.

Hi NoPegs. No, it's the high frequency hum. My question is if it's all NTSC displays, how come there are some TVs that don't emit this hum?
And how do you watch your vintage TVs without getting a splitting headache!?!
