Good question! I have opened the unit twice now, once for dedusting and once to wipe what I thought to be the "read head" with some alcohol. A litte, white, oval protuberance. Other than that, I don't really know what components could need adjustment. This says Head alignment is more sensitive and may require factory alignment disks.
I'm taking a break for now. I've had three really intensive "retro weeks" and I don't want to get fed up with it. ๐
