Fix resistance in stereo output
I believe the answer is:
restore
'fix' is the definition.
('restore' can be a synonym of 'fix')
'resistance in stereo output' is the wordplay.
I cannot quite understand how this works, but
'resistance' could be 'r' (abbreviation) and 'r' is found within the answer.
an anagram of 'stereo' is 'estore' which is present in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for restore that I've seen before include "Repair, put back" , "Renew, repair; give back" , "Bring back to health" , "Bring back, reinstate" , "Repair, renovate" .)
