Find, when you amplify (4,2)
I believe the answer is:
turn up
'find' is the definition.
(I know this)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for turn up that I've seen before include "surprise" , "Appear by chance - increase volume" , "Increase strength" , "put in an appearance" , "make louder" .)
