I use a free bubble app on my I phone and it's dead nuts accurate. I've cross checked it with real bubble levels and they zero out after I set it with the iPhone.
Platter Levelling Issue
I have just purchased a new "bullseye style" bubble level that has graduated markings on it to allow you to determine the degree of misaligned conditions - each marking is supposed to represent 5/1000's of a degree
I initially verified it's accuracy by levelling a flat surface and then rotated the level in the horizontal plane in place - the position of the bubble did not move as I rotated it through 360 degrees.
I then placed the level on the plinth by the base of the arm and levelled the turntable - I believe the mounting method of my arm should ensure the arm is now perpendicular.
I then place the level on my turntable platter and took a readings as I rotated the platter through 360 degrees
Turns out the platter is not quite parallel to the plinth
- I don't think the bearing is damaged, since the degree of misalignment was consistent and always in the same direction as I rotated the platter - so the platter is not quite aligned with the plinth
The margin of error I observed is 10/1000's of a degree according to the gradations on the level
So, until I can rectify this - my questions are...
1. should I ensure the platter is level at the expense of a perpendicular arm
2. should I ensure the arm is perpendicular at the expense of a horizontal platter alignment?
3. Am I being 10-1000's of a degree anal :-)
The arm is an Audiomods Series 3 that has Rega style bearings and from what I have read on the web it is more important for arms with a bearing system like the Rega to be perpendicular
I have read other posts on Agon of a similar nature, but there was no mention as to the degree of misalignment
Any input would be very much appreciated
Many Thanks
