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.

You can always center the stylus over the exact center of both null points. If you want to see pictures of a Baerwald set-up using the Feickert protractor, try page 2 of this thread.

Typically this happens when using a Baerwald based protractor. You rotate the gauge and the swing the arm until it is. For one example of a gage that measures ‘pivot to spindle’, link here. So my main point is when baerwzld are baerwals with the grid it all hinges on how good your eyesight is. The trick is to have the cartridge mounted so that the needle aligns perfectly on BOTH dots without moving the protractor. There are many ways “Solver” can be used to enhance and expand the capabilities of complex spreadsheets.

The method is different.

These are also spreadsheet input cells, but initially they are linked to the corresponding calculator cells, I3, O3, and Q3 so the calculator controls the entire spreadsheet.

The red wire for the right channel on that laignment wasn’t looking all that well.

The default or initial input values are This will involve some averaging of the zenith angle between the two points, but the stylus should find exact center over both null points. It is not the purpose of this page to study or attempt to explain the difference between different alignment theories.

Baerwald Alignment Protractor for Turntables

Perhaps there will be inner grove tracking issues that will be better and I just need more time to identify them. Where did you get that? About a month ago I broke off the cantilever stupid me. Thanks for the correction. Why does every one of these alignment instructions always contain a wrong statement to confuse the beginner? The Magnited States of ‘Murica. The one referenced here: The second cause might be an incorrect pivot-to-spindle mounting distance. Your name or email address: The statement that I refered to makes no sense.

G’day all, in my opinion the whole process is more complex than one might think. I first became aware of the seemingly precise alignment options last year prior to my VPI TT purchase. Deuce66Jan 28, Download All Files 5 20 0 0 0 0 0. The heads of the screws that came with that cart don’t fit properly in a Technics branded headshell, so I had to reverse them. As a word of caution, only six cells on the spreadsheet should be used for entering numbers.

Liked By View All. Stage has shifted a little more left than I’d like instead of more right like beforeand very weak and muffled. I compared the first alignment done by the dealer with the jig and it was off both in the alignment with the grid and the azimuth were off, so much for blind faith.

Other than that, have fun calculating. With 20GB, you have the space you need: The above image shows the two null points in relation to each other. I used the VPI jig and it was quite easy but somewhat tedious. As with the overhang adjustment, leave the fasteners just slack enough to make the rotation but snug enough to hold position. So, the alignment is right if I am looking at it straight on and the cantilever is in a straight line with the line on the protractor?

I used a paper Baerwald protractor and played a record all the way through and didn’t notice any distortion at all.


Aligning cartridge using Baerwald protractor | Steve Hoffman Music Forums

You could ask “Solver” to find new innermost and protractr groove radii that would yield Steven’s alignment null-points, and you would also get a graphical representation of Steven’s tracking error and distortion curves. This time I’m going to go back up to Pittsburgh and put the setup back into the hands of someone who knows what they’re doing. That is our overhang adjustment using a two point protractor. Give potractor Shout Out If you print this Thing and display it in public proudly give attribution by printing and displaying this tag.

Using the VPI jig I only have to deal with the one alignment grid much easier than the 2 point protractors. Akignment in or Sign up. If necessary, immobilize platter I suggest masking tape.

Rotate cartridge to align cantilever with grid.

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. I was first sent a defective cartridge so I got two opportunities to set it up. If you have to average the zenith between the two points, you don’t have the overhang correct. One reason for unlinking the calculator might be to evaluate a tonearm’s geometry by inputting effective length, angular offset, and stylus overhang directly into cells A3, B3, and C3, respectively.

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 the graph and the rest of the spreadsheet. The rest of the guide is correct and well done, but this statment flies in contradiction to the rest of it.
