Current collector’s chart on seasonal entertainment (10)

Ross

I believe the answer is:

pantograph

'current collector's' is the definition.
(device conveying electrical current)

'chart on seasonal entertainment' is the wordplay.
'chart' becomes 'graph' (I've seen this before).
'on' means one lot of letters go next to another.
'seasonal entertainment' becomes 'panto' (pantomime).
'graph' put after 'panto' is 'PANTOGRAPH'.

(Another definition for pantograph that I've seen is " Current line on the street".)

I've seen this clue in The Times.
