7 Analog Alignment Targets - Video #4: Zenith Error

[@iansmith7166]

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

[@WAM-Engineering]

Wow, thanks! We enjoy doing what we do. There are a minimum of 30 video topics in the hopper so watch out for more.

Danke für die deutlichen Worte.

[@mspdec]

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

[@WAM-Engineering]

Thank you, Mark!!

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.

We tried a laser illumination method. One of the engineers on our research team has spent decades in optics engineering and came up with the concept. It didn’t take too long to conclude it a failure. It was more hopeful on certain stylus profiles and less so on others. We are working on a method that does not involve specialized microscopy. Stay tuned.

@@WAM-Engineering ok. what about this DPF digital machine i see people use can that measure zenith? I don't know how accurate it is? it seems to be a good little piece of kit what do you think of it? I forgotten the name sorry! I think it measures most parameters and you can measure azimuth as well.

[@WAM-Engineering]

I don’t know what “DPF” is. Are you talking about a profilometer? We looked at those but the resolution wasn’t fine enough. Azimuth cannot be determined visually at all as it is not only a function of coil orientation with respect to the 45 degree groove wall but is also sensitive to the orientation of the magnetic flux field which we cannot see (without ruining the motor with ferrous dust)

@@WAM-Engineering no it's DSP sorry I've been looking a diesel engines recently😂 I've been doing a search on the internet I found it now it's parks audio puffin DSP phono stagee, basically it's a digital preamp converter but it has these functions of azimuth adjustment I don't know what else it can do? looks like a nice piece of kit what do you think of it?

[@WAM-Engineering]

could be promising. I haven't tried it.@@jedi-mic
