>>SRA, aka VTA or vertical tracking angle<<
This is incorrect and shows a lack of understanding.
VTA (Vertical Tracking Angle) is the angle between the record surface and the cantilever.
SRA (Stylus Rake Angle) also called Scanning Rake Angle is the angle between the centerline of the stylus and a plane that is perpendicular to the record surface.
In simpler terms, SRA describes the angle of the stylus and VTA describes the angle of the cantilever
I hope that helps.
