S & B York – puzzle by Dalibor

Dalibor’s rather unusual contribution to the party can be found here:   Dalibor @ York 2016
In case one still likes to have a go, do not read any further yet from this point onward.

Dalibor is not your guide for Le Tour de York, I’m afraid.
That said, turning 6d and 7d into an ellipsis, gave this puzzle at least some kind of connection to this great city.

There was an advance warning that several clues were faulty.
It turned out to be that all the (full) anagram clues, no less than 11 in total, were lacking the indicator.
But that was only half the story.
Coincidentally (but probably deliberately), in all these clues the anagram fodder was also a well-known anagram indicator.
Therefore, with some imagination, one might say that in each of these clues the anagram fodder was its own anagrind.

The completed grid, highlighting the ‘faulty’ clues, is added at the end of the blog.

Definitions are underlined wherever possible and/or appropriate.
