(warm tips: pay attention to that the phonograph can't rotate when adjusting!)
A simple method for adjusting the azimuth of the cartridge: move the cartridge to the middle of the record, lower the arm, and make the stylus fall on the record. Place the adjusting ruler in front of the cartridge to see whether the cartridge is aligned with the vertical line in the middle of the grid, and whether the outer contour of the cartridge is aligned with the grid line (for the cartridge with irregular contour, it is estimated whether it is aligned with the grid line, and the proportion is uniform)
How to use VTA balance of singing arm:
Move the head to the middle of the record, put down the arm and make the needle fall on the record. Place the adjusting ruler on the side of the arm to see if the arm is parallel to the horizontal line of the adjusting ruler. If not, adjust VTA (i.e. adjust the height of the arm)
