Baerwald, Stevenson, and others came along later, and each published alignment geometry equations. I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. I wound up with.

I ordered the Technics overhang gauge, and printed out the Technics protractor from Vinyl Engine. Outputs are angular offset, linear offset, stylus overhang, pivot-to-spindle mounting distance, inner null-point, and outer null-point.
Showing adjustments to be made. The above image shows the two null points in relation to each other. The second cause might be an incorrect pivot-to-spindle mounting distance.
I first became aware of the seemingly precise alignment options last year prior to my VPI TT purchase. I have to crank the volume much higher than normal to get the usual listening level, and even then it’s muddy.
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. Log in or Sign up. This is the process that I’ve worked out and it works for me! To adjust mounting length, loosen the fasteners ‘just enough’ to allow the cartridge to be slid in either direction within the headshell until the stylus is centered over the null point.

If you have to average the zenith between the two points, you don’t have the overhang correct. It was pre-mounted for a Technics alignment. When it was new Baerwal let the dealer set it up and had complete faith that it was done correct.
What baeewald 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. DarkAuditFeb 1, Danny HollandJan 29, Phil Elliott likes this.

The red wire for the right channel on that headshell wasn’t looking all pprotractor well. In effect the cartridge can’t be moved forward enough to reach the null point.
proteactor Guy at the shop double-checked the wire connections, but said without the TT as well, baerwals couldn’t check the alignment. It is based upon the Baerwald calculations for minimum tracking error when using a pivoted tonearm. Top view showing the two points of alignment. To adjust Zenith angle, the cartridge body is rotated within the headshell until a parallel alignment exists between the cantilever and the grid lines on the protractor. Using the VPI jig I only have to deal with the one alignment grid much easier than the 2 point protractors.
DarkAuditJan 29, Why does every one of these alignment instructions always contain a wrong statement to confuse the beginner? The Magnited States of ‘Murica. I used the VPI jig and it was quite easy but somewhat tedious.
Perhaps there will be inner grove tracking issues that will be better and I just need more time to identify them.
The one referenced here: I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. For advanced spreadsheet users, the Excel “Solver” function is a very baerwalld tool that can be used advantageously with this spreadsheet.

Other types of measuring devices exist but the reader will need to discover these. It is not the purpose of this page to study or attempt to protractof the difference between different alignment theories.
One reason for unlinking barwald calculator might be to evaluate a tonearm’s geometry by inputting effective length, angular offset, and stylus overhang directly into cells A3, B3, and C3, respectively. I’ve used Vinyl Engine as a reference site, mostly for their amazing cartridge library, but for other things upon occasion.
When correctly set, the stylus will have a near perfect groove tangency at two points on prohractor record, minimizing tracking error between and beyond the null points.
