If it is worse then it needs to be put back the way it was.
BTW an interesting experiment for you and all of us would be, to connect the transformer directly to the voice coil without the bucking coil.
This can be done by unsoldering that end of the bucking coil from that post where the voice coil comes in and then running the wire directly to the transformer end where the bucking coil connects to it (you do not even have to unsolder this one).
The goal is to see if this has any effect whatsoever on the hum.
----------
I guess the next thing is to
1) try to swap the voice coil ends (as I said I doubt this matters) and
2) Ground the chassis.
BTW is the hum level really pronounced? Could it be a normal thing?
