Hello. I have a Rotel 1070 preamp on a Carver amp. Never had a Turntable on this system until I received one as a present this Christmas. A vintage Phillips 312 with an Ortofon 5E mm cartridge. With the phono connected (properly grounded), if I switch the preamp to the phono stage I get a very high level of static and noise. Grounding has been checked and rechecked and it is fine. This Turntable was hooked into another system and presented no noise. So the issue seems to be with the Rotel phono preamp stage. Same issue with the power amp off, just listening through the preamp > headphones.
Any advice? Should I get a separate phono preamp and hook it through the aux input? Or should I just dump the Rotel and get a new preamp? I am committed to moving back into vinyl with this system configuration or with a new one. But I am not sure how to proceed.
UPDATE: Problem positively IDed, thanks to Wine Man. It was my powerline adapter setup. See thread, below.
UPDATED UPDATE:
This fix may be of use to others.
So, I was having no real luck reducing my phono preamp stage noise down to a tolerable level. I tried lots of fixes, including trying to ignore it, but it was really ruining my record listening. Finally, in response to Wine Man's suggestion, we IDed the problem, but not the solution.
It was directly related to the plug-in wifi extender system hooked in at our house. These range boosters plug into your wall and use the house wiring to extend the range throughout bigger houses. We require this so that my son has decent reception upstairs for his work and, more importantly to him, his gaming.
We disconnected the range extender as an experiment and my phono noise disappeared -- 100%. Buuuut, no wifi upstairs.
Talked to a tech nerd friend who told me to try an alternative to the plug-in house wiring solution: it's called Moca, made by Motorola. This extender uses the house coax wiring instead of electrical wiring. Our house's cable/coax runs into most rooms, including my son's, so this was viable. We bought it, installed it, and —magically— it worked.
This fix is similar to what Wine Man implemented at his place. So it seems that using coax is the better way to extend wifi reception.
Nomo phono noise, better wifi coverage than before, and my vinyl is now in play once again.
