Channel imbalance with turntable playback

@pragmasis I spoke too soon. The imbalance is still there but it’s on the right side now. I think after listening to the left leaning sound for so long it just seemed more balanced when swapped. I have since swapped the phono inputs back and will continue to trouble shoot. I swapped the red and white cartridge connectors and got a low hum but it sounded pretty good. I didn’t listen for very long because it was late at night and didn’t want to wake the neighbors. Regarding anti skate, I don’t think I can adjust this. I’m running the Clearaudio concept table with magnetic bering tone arm. 

Might be worth trying your TT on a friend's system or at a dealer's to see if it is the source of the problem... the imbalance is unlikely to be affected by the cartridge connectors so probably best to leave those as intended.

I think it's absolutely crazy thread, sorry. 

-Use MONO record to check the imbalance.

-Make sure to buy TEST LP for stereo test (it will help you to understand what's going on).

-Use different stereo LPs to make sure what you're hearing. 

This is what a balance control is for. The best systems frequently require tweaking the balance from one recording to another. Do not swap channels! If it bothers you that much change cartridges. I suspect you have a confluence of errors going on. Something else besides the cartridge is left leaning. Like chakster recommends, a test record will adjust your system to dead center as a starting point. Unfortunately, this does not account for variance in recordings so, it is best to learn to adjust it by ear. I want to hear the same amount of energy coming from both channels. This is different than getting the singer dead center although the singer usually winds up there. Where does the balance sound best to you? You can go back and forth until you find the best spot. But, you have to do this at the listening position so a remote control is mandatory. Running back and forth to the preamp is a PITA.
