I’m the current caretaker of what was my pop’s LP12 with the Valhalla mod and Rabco straight line tracking tonearm. I completely retuned, leveled, lubed and rebelted it a couple of years ago and it sounds lovely.
I liken it to my ‘93 Ducati also known as “the world’s greatest kit bike”; You could enjoy it as is from the factory or heap time and money at it with all sorts of modifications! LOL
Really there is no wrong answer though now I’m thinking of unpacking his old SOTA Sapphire and getting THAT going again
Happy listening
