Turntable channel imbalance

Thanks y’all. 
 

I don’t think it’s the pre. It’s been the case across multiple phono pre amps. (Inbuilt on 2 integrateds + the Rega Fono)
 

Will triple check the level and RCA inputs. It’s strange to me that it’s more present on certain LPs but not others. 
 

would love any ideas on unlocking the anti-skate in this particular turntable. 

It is unwise and often very misleading to judge channel balance while listening to stereo LPs. You have no idea what the recording engineer had in mind when he calibrated the recording equipment. Furthermore, the room itself often plays acoustical tricks that make one channel appear to be louder than the other. The easiest thing to do in a home environment is to play a mono LP on your stereo system and listen for the location of the image. If the image is right between the speakers, you probably have no problem.

That’s a great call. In this instance I referenced the digital copy in comparison. Maybe it was the old mix on the vinyl - but it leans Very left.

@leemaze Your TT has a fixed tracking force of 1.2 grams and the anti-skate is fixed to match the cartridge that came with the TT. The anti-skate is a fixed calibrated spring. It’s a plug and play TT. No adjustments.

You wrote, "In this instance I referenced the digital copy in comparison."  Do you mean to say that you listened to the CD or streamed version of the same music, and it does not seem out of channel balance?  If so, that is not conclusive evidence you have a real problem in your vinyl system, because creating the digital version involved the imposition of more engineering at the other end.  Try the mono LP experiment anyway.
