Comment on Audio enthusiast seeking safety advice
a_non_monotonic_function@lemmy.world 17 hours agoThat is what it looked like, but that surprised me. My turntable is more modern and doesn’t require a ground. As for the antenna, yes, that makes sense!
But am I misreading something… neither of those seems like an actual dangerous situation? Oddly enough the components that I would normally guess were more dangerous (specifically the pre-amp and amp) don’t seem to have a ground circuit exposed despite the two-prong set-up.

They don’t have a power ground to prevent hums. There might be a marginal risk if something comes loose in the amp, but your modern electrical cabinet would have a differential switch to save you in that case. I remember my audio engineer degrounding one of my audio components when in had the issue.
My guess for the audio ground is that older turntables had poorer electrical isolation and power lines were more noisy. For more technical explanations we need an old school audio engineer.

I’m hoping this means that the system is probably safe to use? XD
I’m not really finding grounding needs on any of the other equipment. Even though the power amp, for instance, is something that I would associate with more danger and it only has two prongs, there doesn’t seem to be exposed ground circuitry.
