Is VTA and SRA the same thing?


Hi Audiogoners.
I understand ther refer to Vertical Tracking Angle and Stylus Raking Angle.
What I would like to know is are they the same thing? I mean, every time we change the VTA, let say 1degree, then the SRA will change the same 1 degree?
Thanks,
Calvin

SRA and VTA are used to describe the relationship of individual components to the record surface in degrees.  Once the two components are glued together they are an assembly.  The relationship then becomes a means (VTA) to an end (SRA).
@wlutke Please explain more detail.
Thanks
It means if you are talking about the relationship of the stylus to the record surface in degrees, you say SRA.
If you are talking about the relationship of the cantilever (measured from a line drawn from the stylus contact point to the cantilever pivot) you say VTA.  
If you are talking about a procedure (setting SRA), it is cause (VTA) and  effect (SRA).  Means to an end.
