Headshell Upgrade Questions

Hello Audio Fans . I'm looking to purchase a headshell with azimuth adjustment. At the moment, I'm looking at the At-LH 13/15/17, as they had overhang and azimuth adjustments. Before I spend $40-80 on a fancy headshell, how accurately can the azimuth be adjusted by eye or mirror ? I have no intentions of buying a special $300 Fosgate Fozgometer Azimuth Meter, for a one time cartridge adjustment. Only one cartridge will be installed in this headshell.

Other recommendations for this type of headshell are also appreciated, but I only have one single pin (topside) on my headshells. I will be using the Yamaha YP-701 for this upgrade.

Thank you folks.

The Audio Technica AT LH13 has two "fixed" holes for the cartridge mounting screws.

They may or may not be suitable for your particular protractor setting. :idea:

Thanks Balifly. I found a photo and according to AT's website, there is an adjustment for overhang. There appears to be a set screw on the side facing the spindle, to adjust OH and the clamp part to adjust azimuth. What do you make ?
 
Thanks, now we're talking. Now, how critically close , can one adjust the azimuth, without the use of a $300 meter ?

Thanks Balifly, just won a Yamaha Headshell w/azimuth adjustment. Now, I have found several digital oscilloscopes, that connect to a PC. I'm talking $60, with 2 channels . Will a digital scope like that , work for me, adjusting the azimuth ? Again, Thank you.

My experience with azimuth adjustment are restricted to mirror and some old test records only. :dunno:
 
Got the head shell today, nice. Been playing around with adjustment, sound was improved, widen sound stage. Will play a little more.
 
Today, I got a little more technical , adjusting the azimuth on my new Yamaha headshell. Using a digital volt meter, I started measuring the voltage, as I turned the head shell. I used a test record , with a 1khz test sound. I manage to reach a point , where the voltages where very close.


Next, using a decibel app, on my tablet, I checked the output at the speakers. Well, low and behold, they finally match . Even after re-placing my speakers, using the Sumiko method , I felt that the right speaker was a little dominate, and it was. Now, they are both well balanced. Also, the depth of the soundstage has improved.


Now, I need to keep my eyes out for another one of these Yamaha head shells. One for each of my fav cartridges, Grado/8MZ and Shure M91ED/SAS.
