Monday off for current producer (6)
I believe the answer is:
dynamo
'current producer' is the definition.
(I've seen this in another clue)
'monday off' is the wordplay.
'off' indicates an anagram.
'monday' with letters rearranged gives 'DYNAMO'.
'for' is the link.
(Other definitions for dynamo that I've seen before include "Small generator" , "Monday (anag)" , "Generator of electricity (eg, on bicycle)" , "Type of electrical generator" , "Electric current generator" .)
