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. 

Thank you. Is anti-skate adjustment available on a p-mount deck?  I don’t see instructions for it in the manual. Thanks!

@fuzztone using a Rega Fono MM pre - just on/off. So am I out of luck? Is this the table or the cart?

Thanks @joenies i figured as much. Was hoping there’d be a guide for hacking a p-mount deck. Maybe I should try un-balancing towards the right…

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. 

Fair, @lewm. On vacation currently but will reference a Mono LP and report back. I listened to the remastered CD version Of Zenyatta Mondatta in my most recent listening but I’ve noticed the left lean with many other of my records. 

Hi @joenies its very noticeable on some records, maybe more than 3 db. No imbalance with other sources. CDs have perfect centered imaging. I primarily listen to CDs and streaming. Vinyl is fun nostalgia for me. But some records sound so off I just put on the CD!

I do use an AT SS445E/U high-end NOS cart with original Nude 0.3mil elliptical stylus. I feel like I’d have to spend a bit to get better performance, no?
