Hum in the HT. The 50-60Hz is only in some speakers. My HT uses a Dectet and otherwise almost entirely basic power cables. The hum is only in a few speakers …not all. I feel like I removed the hum from some, but then it went to others. I’ve done some isolating but hear it with everything unplugged (though rca connectors still connected) except the amp. I only have one three pronged thing in the mix. It’s not unbearable, but I hear it and don’t like it.
Additionally, I’m hearing what was explained to me as wifi in my phono tube stages. It’s a bleep and a bloop sound. My tubes are exposed and not under cages. Do I need cages? My router is probably 30 ft away.
