proper way to wire AC heaters?

Ricky	proper way to wire AC heaters? what is the proper way to wire up AC heaters? I recently finished my 2-6v6 amp and have noticed some hum. I'm wondering if maybe I didn't wire it up the best way to remove hum. the heaters are basically wired in paralel to one another, on the 6v6's the two #2 pins are tied together with the same side of AC,same way with pin #7. Is this wrong? should I have made them alternate, with pin #7 going to pin #2 of the other 6v6 and vice versa? how about the two 12ax7? one is the PI and the other is the two gain stages. I'm especially confused about these two since they're like two tubes in one. they are currently wired similar to the 6v6's, withe one side of the AC connected to pins 4 and 5 on each tube and the other side of the AC connected to pin 9 on each tube. I've spent most of my time modifing and understanding amps' circuits but don't know much when it comes to heaters, so, if someone could explain how to wire these heaters up, I would greatly appriciate it. -Ricky
