A two hour drive is well worth it. Putting parts in is not rocket science, but is frequently done wrong. My local dealer has been to basic and advanced technical training. He has seen about every part upside down or on the wrong support, incorrect spring tension, etc and folks wondering what the problem is.
I am not a patient detailed oriented person… so, of course I keep my hands off my turntable. My Linn is an outstanding sounding table… if I had worked on it, it probably would not be.
