Bug found by a famous model's PA (6)
I believe the answer is:
tannoy
'pa' is the definition.
(a public address system)
'bug found by a famous model's' is the wordplay.
'bug' becomes 'annoy' (I've seen this in another clue).
'found by' says to put letters next to each other.
'a famous model' becomes 't' (Ford Model T car. I am not sure about the 'famous' bit.).
'annoy' after 't' is 'TANNOY'.
Can you help me to learn more?
(Other definitions for tannoy that I've seen before include "Sound amplification system" , "Public-address system" , "Public address system" , "Loudspeaker system" , "Speaker" .)
