No, that will short out the B+ to ground. You can take the B+off the 5v center tap, however.
If the same breadboard was quiet with the other B+ supply, your problem is with your new supply.
How are you listening to it to determine its sound? Though the line stage?
Ground the input to the breadboard to assess if the hum is coming in on the input.
DC heaters should be used.
Separate and twist the AC wires.
Phono stages are really hard to get quiet.
