First time posting here so I hope this is the right place. My klipsch R-15PMs have been making this high pitched buzzing sound - gets louder as I turn up the volume, and it only happens on phono mode (even when record player is turned off). In Bluetooth mode it’s completely quiet. It gets louder if I touch the ground wire or the cables in the back that connect to the record player. Any ideas?? I’m completely stumped and it’s driving me crazy! I’m a total newbie so any help would be appreciated.
