Raise one's hopes to put a lot on the turntable (5,3,4)

'raise one's hopes to put a' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'lot on the turntable' is the wordplay.
I cannot quite see how this works, but
'lot' could be 'stack' (synonyms) and 'stack' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
