It takes time and patience to get it just right, but the results are worth it! You rotate the gauge and the swing the arm until it is. In the original, generic, headshell, I noticed the right channel had gone nearly nonexistent.
Why does every one of these alignment instructions always contain baerdald wrong statement to confuse the beginner?
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. This will involve some averaging of the zenith angle between the two points, but the stylus should find exact center over both null points. The default or initial input values are Stopped using the stabilizer, no difference.
To adjust overhang, we must adjust the mounting length between the stylus and tonearm pivot. 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. Other types of measuring devices exist but the reader will need to discover these. If you want to see pictures of a Baerwald set-up using the Feickert protractor, try page 2 of this thread.
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? As always, if you have any questions please feel free to e-mail them to me.
How do you think that the location of where the arm bend inwards, quote: I've discovered that the tracking error is very small as the arm arcs inward from about the mid point of a 12 inch record, and that's where tracking errors are most audible has anything to do with the tracking error? It's really the offset angle that you are referring to, which in the SLMKxx series is 22 degrees. The shape of the arm has nothing to do with the tracking error, that arm can be a rollercoaster model for that matter; the path that the needle is following a theoretical mm which is effective length is still the same.
Hi, You should first push the cartridge forward in the headshell to follow the arc - this sets the overhang. If you run out of room in the slots it may not be possible to use Baerwald alignment with that cartridge. The cartridge should end up 2. Just a "heads up" if you're having trouble printing the protractors and keeping the scale accurate. I found that with the Stupid Protractors I had to print in landscape mode with page scaling set to none.
Thanks for the protractors! I am struggling a little bit and think I may need a bit of advise. With a table designed mounting distance of Calculator reccommended overhangs are not achievable example - I may be able to move the cart out to an max effective length of mm.
I'm using a universal headshell which is similar dimensionally to the original Kenwood, and all original manual specified Kenwood dimensions can be met. So I am confused as to what the original intent for alignment was when the table was designed??
Hi, as you have a much shorter than usual or common arm length, in the absence of a protractor specifically drawn up for that arm, I would simply set the overhang to 9. Providing Kenwood's figures are accurate, your cart will be aligned accurately. It is also possible to check alignment and tweak further by listening to a test record although that usually applies to fine tuning the VTF and anti-skate more than the actual alignment of the cartridge. To be honest I'd be tempted to use an overhang gauge and stick with the standard overhang.
Without knowing the original offset angle it's hard to know what sort of alignment they were aiming for, or what is possible within the current headshell? Thanks for the reply. I could most likley acheive an additional 4 to 5mm of overhang for a max of approx to mm eff. I cannot comment on angle as I have not seen this number published is there an alternate way to determine this angle? I do have the original plastic overhang guage that came with the table, but this appears to place the stylus at the mm eff.
If the plastic overhang guage is used, I assume you would just square the cart in the headshell and call it good? Hi, Yes, if you keep the cartridge square and use the gauge then that will give you the original alignment, which should give reasonable results? If you want to experiment further you could attempt to measure the offset angle the angle between the cantilever and a line drawn between the stylus tip and the horizontal pivot point of the arm , or maybe experiment with inputting different angles into the Alignment Comparator until you get a decent distortion curve, then use Conrad Hoffman's arc protractor generator to print out an alignment template to see if you can align to it?
Thanks JaS I believe that playing with those tools plus the excel spreadsheet is what brought me around to asking these questions! Plotting a Stevenson arc protractor using DIN std for the inner groove radius gives me an overhang of I might just be able to get to this one. If not, I will pursue the overhang guage suggestion. The protractors that dont have an arc offset like the stupid protractor I mean you could align one position but not the other without moving the protractor I thought the whole point was to keep the protractor stationary and then align to both positions, which is not possible with the stupid protractor.
Hi, There seems to be some confusion about how to use these protractors? Neither type is kept stationary between points - for this you would need a specific arc protractor designed for your mounting distance. However, it's not always easy to point the sight-line accurately at the pivot point so if there is misalignment at the second point you should then use it as you would a two-point protractor to correct it.
For each alignment method Stevenson, Baerwald and Lofgren B the two-point protractors above will give identical alignment to the KWillis protractor when used correctly.
What alignment system it adheres to? Is it universal or only for Clearaudio arms? Super simple to setup cartridge with it and the result on my P3-RB is awesome. Better then the Rega Stevenson v. Hi, You won't be able to align a cartridge if you mount the arm at mm. It would require an effective length of Indeed, it's only just long enough to achieve a Can you please suggest me the best protractor for mi Pro-Ject Perspective Anniversary turntable with 9cc tonearm?
Thanks in advance. Hi, Used correctly the Stupid protractor works well - the Baerwald null points will provide the lowest peak error, while the Lofgren B will give the lowest average RMS error with a slight increase at the inner and outer grooves. Alternatively you could use Conrad Hoffman's Arc protractor generator see the thread in the cartridge forum to print out an arc protractor specifically for your arm length - these are quicker to use than a traditional two-point type, but if you go this route be sure to read the instructions carefully.
Dear JaS, thank you very much for your prompt and clear response. Having a properly aligned cartridge not only reduces distortion and gives the best music reproduction, it also insures the least amount of damage to the vinyl's grooves.
To download your own free Cartridge Alignment Protractor, please click the image above. Once you have printed the Protractor it is very easy to use. Simply loosen the bolts that connect the cartridge to your tonearm. Thank you. W ell, there's no place like home.
Home is where my turntable is and everyone should have a two point protractor. In Use: The trick is to have the cartridge mounted so that the needle aligns perfectly on BOTH dots without moving the protractor. What you may need to do is mount the cartridge a bit loose and slightly move it forward or back and see how it aligns on both points.
You know you have it perfect when both points are perfect without moving the protractor. It takes time and patience to get it just right, but the results are worth it! Click here for cartridge alignment tool. Click here to view the two point protractor in action.
