Move the cables around as MC suggested. It makes a huge difference for me with LOMC’s. Not unlike moving rabbit ears back in the day.
A SUT will probably boost the noise too. Unless you attach it directly to the cart.
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.
