SJTony Posted January 31, 2022 Share Posted January 31, 2022 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. 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. Thanx, ~Tony Quote Link to comment Share on other sites More sharing options...
spectrum Posted February 1, 2022 Share Posted February 1, 2022 I’d say buy a cheap phono pre amp on Amazon to do some A/B testing. Return the cheap one when you figure it out and upgrade if needed Quote Link to comment Share on other sites More sharing options...
hoytis Posted February 1, 2022 Share Posted February 1, 2022 Is the static/noise happening just by switching to phono on preamp...or does the turntable also need to be powered on to hear it? Or is it only happening when dropping the needle? Quote Link to comment Share on other sites More sharing options...
SJTony Posted February 3, 2022 Author Share Posted February 3, 2022 UPDATE: Problem 100% IDed: Got a tip on the possible source and it turned out to be dead on. We have a NETGEAR powerline adapter hooked up to get internet from the back 1st floor to the front 2nd floor of our house. Disconnected it tonight and the noise was 100% eliminated from my phono stage. After hearing the suggestion I started searching the problem on the www from that angle instead of from the Rotel angle, and I found out that this is a very common problem. Now at least I know the source of the problem, next issue is how to keep good connectivity throughout my house and still use my phono. That should be solvable, now that I know what to solve. Learning this saved me from buying a new phono pre, or worse, a new full preamp - neither of which would have made any difference. Quote Link to comment Share on other sites More sharing options...
bjorn Posted February 6, 2022 Share Posted February 6, 2022 I had a similar issue with my amp picking up powerline data signals, luckily switching to another outlet solved the issue right away. Quote Link to comment Share on other sites More sharing options...
