Part of a record player (9)
I believe the answer is:
turntable
'part of a record player' is the definition.
(I know that turntable is part of phonograph)
This is all the clue.
(Other definitions for turntable that I've seen before include "part of record player" , "For records" , "Revolving platform" , "Old record-holder" , "Rotating platform" .)
