The Classic's manual clearly instructs the owner to use a 40-weight oil. Even though not SAMA, the bearing seems the same as on the motor of my old Scout. I used 40-W and it worked just fine, and it did not seem "too heavy." The only challenge was to apply it cleanly on the bearing through the tiny space between the spindle and the brass piece. Why would VPI recommend a maintenance product that does not work well with their product after all the years in the turntable business?
