No, unfortunately, it is not possible to get a tutorial that is no longer available, since that means that it has been 'retired' for one reason or another.

Keep in mind, though, that sometimes tutorials are put out circulation for revisions, that is, the author might be doing updates and it could soon be available again. So just because you cannot find a specific tutorial today, it doesn't mean that it is permanently retired. In fact, at any given time, there are several tutorials being updated, during which time they are temporarily unavailable.
