The mirror method gave false setting by 2 or 3° in my case!

Correct - because it doesn't take into account whether the stylus is glued on 'true' to the cantilever.

Some remark to the tracklist:

I have a test record with tracks cut at various angles respective to vertical, like 40°, 41°, ...., 45°, 46°, .... 50° in 11 tracks left channel modulated only, and same 11 tracks right channel modulated only. Minimal feed-through from left to right (or right to left) should be present at track #6. It can be checked by ear or by an oscilloscope. 30dB @1kHz is generally a good value. The mirror method gave false setting by 2 or 3° in my case!

Such alignment tracks could also be added to our test record.

That would be great! 🙂

I wonder how such test signals can be generated by electronic means. I suppose it must be some convolution, but my math knowledge stops here.
I attached the relevant information from my test record.

I use the crosstalk method for azimuth and it works well. VTA can also be set by checking IMD. The test LP should incorporate both.

Shouldn't we proceed with the preparation after a long break?
