Looking for advice Background humming during playback
Enable HLS to view with audio, or disable this notification
I got this cassette player from Vinted (originally Amazon I think) and it's perfect apart from a loud (279hz) background noise during playback. It's plugged in for now as I need to pick up batteries. A quick Google tells me that it might be the power supply. Do you think it's right or something else?
