Thanks!Very informative.Proper alignment is the key to great analog sound.

Lovely music. I think it's the piece Hannibal Lecter was listening to while he was in the cage being served dinner. Oh god...

I'm putting millimeter paper on a spindle with a hole cut exactly in the crosshair.I draw a thick line from the spindle with a vector to the center of the hand support.Then I mark the point of the protrusion on the millimeter paper with a pencil.Then, using a template with a pencil in a movable mandrel, I draw a radius line along the paper from the extraction site.Then I place the cartridge along the line according to the effective arm length.

Ideally the secondary bearing point and the main bearing point should have the same offset angle as the cartridge, which is approximately 23 degrees for a 9" arm. My concern with this design is that the primary bearing and secondary bearing are not at the same height which can create inaccurate azimuth during vertical movement. Not really a mature design to be honest. I much prefer the way Continuum Cobra or Copperhead is designed, not counting the price difference.

I had no idea Vince Vaughn was this smart!

keep up the good work!!

Thank you so much WallyAnalog fans👇

Hi I've got this dilemma maybe you can help me with?? I'm trying to work out this settings for this s-arm on a turntable that is pre-made I'm having a problem with the calculator on vinyl engine, I'm assuming it must be right but it's giving me strange responses or I'm doing something wrong! When I put in the spindle to Pivot distance what is 215mm and the effective length is 246mm with a overhang of 15mm in the VE calculator I can't get anywhere near the pivot point with this measurement? I could never reach the overhang either what it is at 15mm. Even if I try and set it to a Technics specification what I got off the internet for the sl 1200 what has the same pivot to spindle distance that is about 230mm effective length always gives me overhang of about 17... mm. By the calculations the arm is way too long at 246mm I was wondering because it's an s shaped arm but I believe you measure it the same way. So I don't know what's going on I need to cut the arm shorter but that doesn't seem to tally up with the overhang of 15mm if I do that? Thanks I suppose I could draw an arc with a 15 or 14 mm overhang at 230 and see what happens. I've been feeling about with degrees to see what the calculator is giving me and about 21 is probably on the money with a lofgrem b setting. None of the null points seem to be anywhere close to any of the known out there! the arm tube was bent and I did straighten it and had a degrees of 22.5. The cartridge is in the middle of the slots on the headshell what is part of the make it's not a aftermarket what looks and you assume is correct? Do you know better calculator I'm not sure if the ve calculator is giving me the right figures? Something doesn't tally up and I can't work out what it is! and yes my measurements are correct checked about five times now I'm a bit worried committing to cutting this arm!!? Condescend what's going with the calculator it doesn't matter about what type of specs I put in like angle with that length of 246mm it gives me pivot to spindle completely different?? it's got to be 215 mm I can't change it any advice would be welcome thanks!

Very clear video. It's maybe worth noting that the internal horizontal torque force can be negative as well as positive. With my arm it's -1% at the outer point and 0% at the inner point.

Great demonstration JR! It seems to me that the coefficient of friction may not change very much with rotational speed in a /silent/ groove, but when there is signal it's a different story. The average vertical deflection of the cantilever is determined by the overall drag force, which is affected by signal strength/frequency, because some of the transverse work in driving the cartridge motor resolves as pulsating longitudinal drag. I doubt that a silent groove will indicate the average angle of the cantilever during average-amplitude music, and it's playing music that matters. Keep up the good work! Richard

Always improving.

The sound level on this video is very low. You may want to redo it.

Hello, I 'd like to get your take on the Kuzma Stogi S unpivot straight tonearm, 9" can you tell me your thoughts ? At the moment I'm using the Pro-ject 10 extreme carbon tone arm. Would like to know if you think I would hear a significant difference. Thank you making the turntable set up video dvd, extremely helpful JP

I understood the "inner-groove distortion" concept pretty well, but this is the best I have ever seen it explained. Funny, I first learned about the linear velocity concept from LaserDiscs. Some had "constant linear velocity," while others had "constant angular velocity." Adjusting null points for the modern double 45rpm editions with less information towards the center is brilliant.

A problem with arc protractors is that you are assuming that the tonearm is accurately mounted at the correct specified distance from the spindle. This is frequently not true, especially with arms that have post held by a single grub screw in an arm collar attached to the turntable plinth,

I love your total honesty and transparency, rather than just resorting to spouting various views as facts as others do. I decided that once I had set the cartridge and arm up, if it sounds ok then just leave it alone, as the SRA will be different for varying record thicknesses anyway! Also, I suspect most cutting engineers just eyeball it with their experience. As long as they are getting a continuous stream of laquer swarf, they won't care what the actual angle is!!. Great channel, and look forward to your updates on the subject.

Hi JR. would an articulated headshell lockable pivot be something to explore to allow sra adjustment ? Thanks, Tony

Great video as always, great deal to learn from you. Keep up the great work for our wonderful analog world. What’s the name of the grey rabbit in the closet 😊.

I have a Pure Fidelity Encore , with Acoustic Signature TA- 1000 9’’ tonearm . Use a HANA ml, retipped, Boron Cantilever and nude Micro Ridge . I sure need to be perfectly setup to perform well.

Excellent video on the simplicity of the process once you send in the cartridge

На слух получается настроить,если есть в тонарме регулировка VTA во время прослушивания.На Dynavector 505 это прекрасно.

How about skipping ALL of this and just using the AnalogMagic 2 software to find the best performing Azimuth, VTF, SRA, etc.!

Danke für die deutlichen Worte.

Danke für den Aufwand um Aufklärung zu betreiben. Die Zusammenhänge werden deutlich von Technik und die Auswirkungen dazu.

Hmm, I just finished watching this series and I have 3 turntables with no adjustable VTA at the tonearm (Technics SL-2 and SL-Q2, and Rega Planar 2). I only have one headshell that has an adjustable azimuth. I use a sight glass to get the tonearm as level as possible and have adjusted the VTA by switching around platter mats. I'm not sure If I could get these kind of exact results with my turntables.

Hello J.R, thank you for the new videos, this is a great tool and I am glad I have the new version. It is interesting to see how much the measurement changes just by twisting the cable coming out of the arm tube on the 4Point. Result is fantastic...

FWIW, the 1x on the microscope means that the image at the focal plane of the camera is the same size as the object that is in focus. Since the sensor of the camera is tiny, when it gets displayed on a monitor it will of course be much larger.

do you offer services for more vintage cartridges with not much info about them out there? i have an audio technica at-32 that recently got retipped to be microline also, how would the service differ for turntables that also dont have much data on them, since i have a kenwood kp 1100 and the internet has provided many conflicting examples of how much the tonearm weighs for example.

Thank you, Michael!

That was VERY INFORMATIVE. This explains everything I was concerned about and very well explains SRA and necessary angles

Hi J.R. I agree, this tool has been the greatest tool for helping me to achieve the sound I desire from my table other than a VTF scale. Don N.

Great video! A wealth of information on this channel 🍺

Dual pivot added friction leaves more performance on the table than the arm in standard form. Plus, you have to constantly monitor its performance. No thanks.

Great explanation! My sole gripe with this video is that I align my turntable with Loegren, same as you,... yet the old/new arcs comparison was shown uniquely with the Baerwald arc. Is it because it was more visually striking or due to most people preferring that arc, or some other reason? The same data being shown through a Loefgren graph would have been the cherry on the sundae, IMHO.

Another great video J.R. Thank you. Let's hope you can get the lathe engineers on board with your optimization techniques.

Fantastic video (as always). Thank you J.R. 👍🙏

My gosh, you are so nerds! Listen to the music - will you? Cheers from another vinyl nerd. :)

You are the coolest channel for vinyl lovers! Thank you very much!

Dear author, thank you!Sometimes users use test plates.Now we can conclude that we cannot rely on test plates.Super channel!You give a lot of useful information to achieve the perfect vinyl sound.Thanks!!We are waiting for new videos.

Couldn't you use a little device using a little cat laser toy pointer, and some mirrors, if you had a device Where You place the needle in the centre a bit like a weighing machine you lie the laser in the horizontal and there's a small mirror reflecting it up through the tip of the stylus and on the side two mirrors with markings to see what the readings are at 90 degrees to the centre.

Hello.And isn't it necessary to direct the vector of the line of the spindle template exactly to the center of the tonearm support? and immobilize this template.And then set the effective length of the tonearm?with respect.Thank you.!

Hello.Thank you for discovering something new.I think that a slight violation of the azimuth of 1.5 ° will not lead to a loss of nuances in the sound.Probably, in this case, a well-tuned tonearm with one support does a good job.And classic tonearms, to which the cartridges are selected correctly in accordance with the reference values, should pass the modulated groove well.Not noticing the slight azimuth deviation when cutting with a milling cutter.But in general, of course, we need to remember what you have told us.After setting up always need to listen to different compositions and make small adjustments.Thanks!Very informative.We are really looking forward to interesting videos.

To my opinion any highend cartridge which shows more then 1 degree deviation should be sent back and money returned. Great video, well thought presentation, compliments.

Many thanks for your hard work for helping us to understand the engineer of music. Two questions. Why do we need Shim (?), when you can adjust height of tonearm. Will you offer the same service for Koetsu with Arche headshell and SME 3012R? Happy weekend 😊

I bought a wooden head shell a while back I lined everything up with my protractor etc the records sound amazing. But I did notice when I put it on my over hang gage it was not in the center? the whole cart was off to one side? I did measure the slots with a caliper & found out there was a 20 thousand difference per side. Question is is it ok or not? should I file/ machine the slots to make the cart in center? I can sent you some photos if you like! any help would be great! Thanks

modification totalli Thorens TD- 160 , Jelco St-550S what do I need for my best sound setup

wow

Nice vid tutorial

Thanks!Before starting to adjust the positioning of the cartridge, I always show the client a video of the passage of the stylus along the groove under the microscope.Seeing how the stylus passes along the modulated track, you can explain to a person why fine tuning is required.Namely, the correct selection of the cartridge according to the reference values to the tonearm is necessary, the correct adjustment so that the stylus passes correctly, without loss of musical moments.
