Be sure the speaker field is not connected to anything. Measure with a high resistance VOM like a Simpson 260. If there is still an indication of leakage then the speaker field coil needs to be insulated from the frame of the speaker.
The method to insulate will be predicated in being able to remove the field coil from the speaker. Cleanup the pole piece and wrap on layer of Kapton tape. Too much tape and the coil will not fit.
It is not a good idea to float the frame of the speaker and allow it to be live at full B+...
