I have had a similar problem always a hum from my old Dual record player. Tried every advise on any forum. No change! Till finally someone gave me the solution that worked. Clean or renew al the connections from the needle to the outgoing plugs of the recordplayer. Problem solved, really. I was in he process of writing the same as boomerbillone bit posting did not work for me.
Has anybody never been able to solve a hum static problem with a phono pre amp?
I have had for years now a hum/static problem with my phono pre amp. I have not been able to listen to analog for too long a time. Let us just say for years. I have localized it to the phono pre amp when it is just attached to the pre amp and amps. Nothing to do with the head amp and turntable. I have tried 3 different models and it is the same problem. I have tried every single piece of info I have found on audiogon and the internet. Cheater plugs, giving it its own socket, grounding it to every piece of equipment, moving it away from system, moving router, making sure connectors are shielded... I have even had two turntable experts from the NY tri state metro area come over and they cannot figure it out. This was not the case when I got it initially. It was dead quiet. But I changed my setup from a Toshiba black box to a flat screen TV and that’s when the problem started. That’s how long it has been. But to be honest I had that black box long after people had switched to flat screens. TV wasn’t that important to me. I sometimes think at the same time somebody in my apartment building or surrounding dense city area put up an antenna and it is causing interference about which I can do nothing. As I said I live in a large apartment building so I cannot rewire.
Has anybody else not been able to resolve this problem and had to give up on analog? Digital is perfect. It is so unfortunate because vinyl has an intoxicating compelling sound like nothing else.

By unplugging the tv I was able to eliminate the hum and static. But when I put the head amp on the hum and static comes back. I still have to figure that out. When I take the head amp out of the equation and there is no hum and static I did notice a slight hum when the needle touches the surface of the record. Take the needle off then complete silence. Is this because the prongs of the cartridge need to be cleaned or reset? |
Hi OP! Good progress diagnosing that. Don't worry about your cartridge. This is telling us you have a noise issue, either radiated noise from the TV or it's an AC issue. The TV is putting noise into your AC line which you are picking up. Phono preamps are incredibly sensitive to this. Make sure you are using fully shielded interconnects. So the next question is,m is your TV using Wifi or Ethernet? If wifi, try switching to Ethernet as an experiment. If it's already on Ethernet and still causing you issues, you may want to use a good power conditioner, but honestly this solution is iffy. Better to relocate your gear away from your TV. If you do use a power conditioner, keep your TV outside of the cleaned outlets. |
