E-M-field problem

[briansune]

Hey do any one know the affection of EMF between transformer, cause I'm going to put all the component together@@.

So i would like to show the design. Hope some one could he me on this> THANKS

If I was building this, I would leave the output transformers where they are and move the Inductor (Choke) and the Mains transformer over to the right. Keep the air gap of the Inductor (Choke) to the edge of the box.

 

[briansune]

Ya you are right this may reduce the EMF affection between the output and choke or main transformer. Bur the look of this will become a little odd.~~ But thanks for your ideas~

 

[briansune]

Sorry for the typos

The general rule of thumb when placing inductive components tightly together is to orient the coils 90 deg from each other.

[briansune]

do you mean each of the transformer should shift 90 deg to each other?

 

[GloBug]

Yes the coils should be 90 degrees in relation to each other.

 

[briansune]

Do you mean this??

 

[Palustris]

That's correct for orientation, but the point was made that the choke should be in the corner not in the center and the same with the PT; so put them over on the left edge. If you are using a rectifier tube it can probably go between the two PS transformers. The output transformers will be between your highest EMF generators and your signal tubes which will be in the space to the right. Distance is everything with the EMF so put your PS as far as possible from your signal components; that's just basic good layout practice.

 

[briansune]

YA but i'm not quite sure the terms of PT PS transformers
And the highest EMF generator will be the Main power transformer~

And the highest EMF generator will be the Main power transformer~

If your power supply is choke input, don't be surprised to find the choke puts out the most severe field. It can be nasty due to the amount of voltage swing and the sharp transitions each 120Hz cycle.

This is not explicitly about transformers, but still, very intersing: Placement of coils in crossover networks
