Ok to adjust balance to achieve center vocal image?


I have an all analog tube vinyl system and don’t remember having to adjust my balance setting in order to achieve a center vocal image. I do now though. I’m getting a left leaning vocal image with the balance set to zero. Is there a good way to see if this can be fixed so I don’t need to balance adjust to achieve a center vocal image? Could it be a preamp tube going out? Something else? Any harm in just continuing to adjust the balance - meaning am I experiencing any signal loss doing so? 
Thanks! Paul

Wayward imagery can be caused many things that may drive mad someone. I would include the following for checking,
Use a cd player to confirm that image is center.
All Recordings are not the same, check with a test record for center voiceNot matched tubes in phono stage, swap tubes L/R to check that image is the same or not.
Align correctly your cartridge, overhung, hta, antiskating (use low), azimuth.....
In most of cases your answer is there.
Speaker positioning, toe in-out, same tweeter axis, moving front to back as rooms are not perfect.Swap L/R cabling.
