I found the source is the rca interconnect cables from turntable into preamp phono input. When I remove the rca cables from preamp it goes away. Just curious if a step up amp will raise the level of signal enough to cancel out the rfi interference. Really a bummer as the Levinson No 526 has a great phono preamp.
Phono amp picking up radio station from turntable rca’s
So just got a Mark Levinson preamp with built in phono preamp. Running 2m rca interconnects from turntable as it sits away from other gear and now picking up a local AM radio station. What are solutions to remove this other than moving turntable and 1 meter rca’s. Would a step up transformer work ? Before my setup was phono preamp next to turntable with short interconnects and running Balanced XLR 2 meter cables to preamp and did not have this issue. Any help and suggestions would be appreciated.
