  Yes, artificial center tap is the way to go... if no actual CT.
  
  Wrap the two heater lines together and with the two resistors making an artificial CT --- you'd be surprised how quiet the line is. Keep the heat lines above the socket surface and away from signal lines.

    This is the diagram exactly like I have it now any tips or hints before I test?

      You sure you want to run the 12AX7 after the 5670? I thought you wanted one line with no TS and the other one with a TS. I think the gain stage with one 12AX7 as input tube is sufficient for your needs.
      
      Just run another input into the 68k-ohm resistor before the first half of the 12AX7. OUT #1 from the 5670 to the bass amp input --- not connected to the 12AX7. OUTPUT #2, into a separate input of the bass amp.
      
      Have each input jack ground out, when not in use. Then, plug the bass guitar into whichever gain stage that you want (no stack or tone stack).
