Musical equipment; see sort provided (7)
I believe the answer is:
stereos
'musical equipment' is the definition.
(I've seen this in another clue)
'see sort provided' is the wordplay.
'provided' indicates an anagram (I've seen 'provide' mean this).
'see'+'sort'='seesort'
'seesort' with letters rearranged gives 'STEREOS'.
(Other definitions for stereos that I've seen before include "Music players" , "sound equipment" .)
