BAERWALD ALIGNMENT PROTRACTOR PDF

ok, you say ‘I knew baerwald protractors, Loefgren protractors, what is that Stevenson it’s somewhere on the internet), Stevenson shed a new light on cartridge. THE REGA BAERWALD ARC PROTRACTOR download this protractor oops, impossible for me to set up my cartridge using your protractor: two possibilities. I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. I wound up with.

However, if the protractor is paper, you may have to settle for aligning the cartridge body alignmdnt parallel to the grid since it will not be possible to get a visual fix between the grid and the cantilever. I prefer to use the Baerwald alignment whenever I can for its slightly lower tracking error values, however if it becomes necessary, a different protractor may be needed with some combinations of tonearms and cartridges.

The trick is to have the cartridge mounted so that the needle alibnment perfectly on BOTH dots without moving the protractor.

Depending on how well you align your sightline you may be way off. However, the tan colored cells may easily be unlinked from the calculator simply by entering numbers into them. When correctly set, the stylus will have a near perfect groove tangency at two points on the record, minimizing tracking error between and beyond the null points. Stage has shifted a little more left than I’d like instead of more right like beforeand very weak and muffled. There is no possible adjustment, right or wrong that would prevent you from achieving this.

Inputs are effective length, innermost groove, and outermost groove. Download All Files 5 20 0 0 0 0 0. Where badrwald you get that? Typically this can happen when pivot-to-spindle distances are made adjustable at the arm board, or if a different tonearm has been incorrectly installed to the turntable.

It was pre-mounted for a Technics alignment. You rotate the gauge and the swing the arm until it is. Click here to view the two point protractor in action.

For one example of a gage that measures ‘pivot to spindle’, link here. Home is where my turntable is and everyone should have a two point protractor. Outputs are angular offset, linear offset, stylus overhang, pivot-to-spindle mounting distance, inner null-point, and outer null-point. Y ou’ll find an Excel file at the link located below this article.

No matter how bad the overhang is you can do it. This weighted curve places more emphasis on tracking error for inner grooves than for outer grooves, which is representative of the actual distortion caused by tracking error.

A special gage is required. Videos Enjoy the Music. Alignmenr Hoffman Music Forums. For example, suppose you wish to evaluate Steven Rochlin’s alignment tool, which has alignment null-points at approximately 70mm and mm. They are the three yellow cells, I3, J3, and K3 in the calculator at the top of each page, and the three tan cells, A3, B3, and C3, which control alignmdnt graph and the rest of the spreadsheet.

I first became aware of the seemingly precise alignment options last year prior to my VPI TT purchase. I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. Danny HollandJan 28, TerrySJan 29, You know you have it perfect when both points are perfect without moving the protractor. But the goal is to adjust the overhang so that the zenith angle is correct at both null points when the stylus is centered over the null point.

In effect the cartridge can’t be moved alignmsnt enough to reach the null point. Okay, so how does the spreadsheet work? And if you have to average the the zenith between the two points, you don’t have the overhang set right. The above image shows the two null points in relation to each other.
