When the horizontal adjustment has been performed,
the vertical position of the turntable is checked with
7" reels on both turntables, and the tape correctly
inserted in the tape path. Check that the tape runs
freely between the flanges of the reels in all positions
of the operating lever. The turntables can be raised
or lowered by adding or removing turbax washers
type M307 between the flange 200549 and housing
200628, see fig. 4.29. Recheck the horizontal position
of both turntables.
