I replaced the heads on an old beta 11/111 VCR. How is an eccentricity adjustment performed on these machines, as I cannot seem to get the heads aligned properly?

After removing the upper fixed drum and mounting the gauge, do this: Adjust the gauge so that it reads about 5 microns. Loosen the mounting screws just a little. Rotate the head by hand slowly. Now tap the head into position so you have a MAX deflection of 3 microns per 1 head rotation. With 5 as your base number your deflection should be between 3.5 -6.5 microns. It takes time but if you are patient you can get it down to a 1 micron deflection.
