Turntable troubles

Do other sources behave the same or is this just an issue with vinyl playback?

If this condition only happens with vinyl, Switch your left and right leads from the table to he preamp so that the left channel of the table is playing through the right channel of the preamp. If the balance swings to the left channel, the problem is with the cartridge. If the balance still favors the right channel, the issue is with your electronics.

Sounds like it (speakers/cartridge) could be out of phase, if you just hooked up the speakers or cartridge recently check that your wires(red +black) (red,green,blue,white) are correct. If you haven't messed with anything recently it could probably be a number of less easy fixes. I'm not sure where you would start though to be honest.

I had this problem. Thought maybe it was my needle or anti skate. Turned out to be a bad cold soldered joint in a RCA cable. You have to be very systematic in trying to diagnose and isolate the problem. Good luck
