Zenith Adjustment Device

Do you know your zenith error? Correct it!

Years ago, we were instructed to align our cartridge body at the protractor null points to achieve ideal alignment. Later, Wally Malewicz gave us the original WallyTractor and a way to improve upon this by aligning the cantilever at the null points while also removing parallax error.

However, we haven't had a way to align that which REALLY matters when setting your stylus/cantilever assembly for ideal horizontal alignment: the contact facets of the stylus that read the groove walls. 

Your cartridge is in perfect alignment on the horizontal plane when a line drawn between the two contact facets form a straight line pointing at the center of the record. This straight line SHOULD be perfectly perpendicular to the cantilever - which is MUCH easier for us to see and therefore align for optimum playback quality.

However, most all high-end cartridge manufacturers work with +/-5 degrees of tolerance with their stylus mount accuracy - though we have seen as much as 14 degrees off of perpendicularity with the cantilever. This means that even though you aligned your cantilever perfectly at the null points, your stylus could be badly out of alignment - completely nullifying your best efforts to achieve minimum tracing distortion.

This zenith error (which, as a function of visual alignment is alternatively referred to as angular error) can cause you to experience quite audible tracing distortions without being aware of it. You are not likely to notice that the soundstage isn't as wide and deep as it should be. Nor will you notice the imaging isn't as pinpoint as it could be. If your stylus isn't properly oriented in the groove, dynamics will be muted, high-frequency extension dulled and the "suppleness" that vinyl playback is known for is just not what it could be if the zenith error were corrected for. 

For now, the only way to measure your stylus zenith error is with very high quality microscopy like that which we use in our Cartridge Analysis Service. However, we are currently working on a method that would allow anyone to measure zenith error at home. 

The solution to MEASURE zenith error is coming in 2022!

The WallyZenith is for use when you already know what your stylus/cantilever zenith error is and wish to make a corrective alignment. It is possible, though a bit tedious, to use the WallyZenith as a measurement tool for zenith error. It is a bit tedious as it involves repeated listening and subjective assessment. WallyZenith is a corrective tool first and foremost. 

In addition to offering the ability to align the stylus contact edges to be perfectly parallel with the record radius and thereby read the left and right channel grooves simultaneously, the WallyZenith allows the user to align for ideal cartridge azimuth BEFORE aligning the cantilever.

Using either the WallyReference (or the customized shim included with the WallyTools Cartridge Analysis service) to quickly and easily align azimuth followed by an alignment of the cantilever with the WallyZenith saves an enormous amount of time and hassle and ensures maximum playback optimization with the greatest accuracy and ease.

It’s easy to hear the benefits of corrected zenith. The high frequencies become clearer. Soundstage is much better defined. It’s sound like everything is “in phase”. With WAM Engineering-corrected SRA, azimuth and zenith my analog setup has never sounded this clean, well-defined and three dimensional.

An incredibly easy to use shelf pin hole jig
Size: 11 Holes, Size: 11 Holes
A solidly constructed jig used for easily creating either a 5mm or 1/4" shelf pin holes. Mark your control line and place the jig on it while using two thumb screws that act as both a clamp and edge guide for perfectly aligned holes. Various thumb screw holes allows for holes that are closer to the edge of your work or for holes further in from the edge.

Good product
Size: 11 Holes
Works well for the must part. I ended up buying a different style bit collar stop because the one provided wasn't solid enough for me. Might be a personal preference

Awesome tool
Very easy to use, only issue I had was the location pin was a bit tight. Chucked it in the drill and polished it up with a scotch-brite and it worked perfectly. The end to end symmetry made it easy to move from one side to the other. Good price as well!

Excellent 11 hole jig
Size: 11 Holes
This jig worked excellently. It doesn't have any instructions, so I watched the video of it. I set it up the way the video showed, and I got decent results. Deducted a star since no instructions.
