Yes, when I changed my source control from an Audio Refinement (YBA, 3.8 volt output rating) preamp that might have had a grounding issue or two to a new Atoll IN200 Evo (latest model integrated, 1 volt output rating). Salience / Jasmine LP 2.0 mkII stage was not super noisy but I definitely noticed some noise with the older preamp vs the dead quite background using the IN200 Evo.
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.

Since this is probably RFI, balanced operation may not help but is always a bit better as far as pure hum issues related to grounding. Can't hurt to try it except in the pocketbook. "Toshiba" is a reference to your old CRT TV, correct? At least you have narrowed down the problem to the degree you can eliminate it by unplugging your flat screen and probably also the HA3000. Since unplugging the flat screen helped a lot and made at least me think it was the sole source of the problem, I am a bit puzzled about the HA3000. That result makes me wonder whether there is another source (not the TV) that is the root source of RFI. |
Hello roxy1927. It is possible that the connectors at the end of the tiny wires that slide onto the pins of the phono cartridge have oxidized. Slide the conectors of the pins and see if they seem tight enough. Clean the pickup's output pins and slde the connectors on and off 5 - 10 times to be sure they are making solid contact. Are the soldered joint when the wires are attached to the connectors in good shape? Check the joints where the tone arm wires connect to the output sockets of the turntable. Good luck! |
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. |
