Red is B+, Blue is plate of output tube.
Black to one end of the hum-buck winding and the yellow to the voice coil.
RESTORE the original connection of the hum-buck and the voice coil to complete the voice circuit in the speaker.
If there is a background hum, try swapping only the yellow/black on the voice-coil/hum-buck. Do not alter the connection of hum-buck to voice coil.
If the hum goes away or gets less, keep, if not swap back.
