Agree with the others. Wood can be finished in many ways with many different materials. Oil? Shellac? Varnish? Wax? Polyurethane? Matte? Satin? Gloss?
Attempting to refinish one part of an older wood piece without knowing anything about the original finish is guesswork. With so many possibilities, most guesses will be wrong and some may cause problems that can't be fixed.
Your results make it evident that lemon oil is one of many possible wrong guesses, so stop applying it. Ask SOTA what the original finish was. If they can't help, ask a local wood finishing expert. They need to be local so they can actually see and touch the wood. I know everything on the internet is true, but no one can deduce your turntable's wood finish from a distance. ;-)
