It would help to know which '80uf' cap is giving off smoke.
If the power transformer was stressed to the point of crackling, it very well may be bad now.
I do not see how the PT could make a cap smoke.
It appears that the initial problem may not have been found.
(or a new one was introduced)
Seeing that you did all of that replacing of parts, it may be wise to go back & check your work.
I would remove all of the tubes before powering it up again.
