Phone for a new bowler (6)
I believe the answer is:
blower
'phone' is the definition.
(informal term for telephone)
'a new bowler' is the wordplay.
'a new' indicates anagramming the letters.
'bowler' anagrammed gives 'BLOWER'.
'for' is the link.
(Other definitions for blower that I've seen before include "Telephone (informal)" , "One producing current" , "Fan - telephone (slang)" , "Speaking-tube" , "Fan; telephone (colloq.)" .)
