I agree with HiFiharv. The platter is concave so the record slopes toward the spindle when clamped. The cartridge therfore should be slightly tilted to maintain the proper azimuth with the record groove. It would be normal then for the paddle to be slightly tilted in the fluid cup and NOT perfectly horizontal.
Well Tempered Ref. Arm
I've noticed that when I look at the arm,in the area where the strings attach to the paddle,I notice that the flat upper portion of the paddle - where the arm attaches thru it - does not sit perfectly parallel;it's tilted maybe 8-10 degrees from perfectly level.Is this a problem? Should this be perfectly level?
