Agreed that if transformer ever smoked it is compromised. However if the HV windings are checking out OK, and filaments are lighting without overheating, there is faint hope. Of course put those HV windings under normal load and you may have a problem, even if all the rest of the wiring is correct and the rectifier is good.

As a safety measure I would replace the transformer and install a fuse.
