Isn't this suppose to be a technical and exact science?

Come on IanB, this is the beginner section FFS!

Yes, this is common and is caused by capacitive coupling between the windings.

OK, a little harsh perhaps. I just thought a little more effort could be put into formulating the question.

I tought maybe the tranformers where to close to one another...
They are cheap too : 10$ each.


I like that:  "Yes, this is common and is caused by capacitive coupling between the windings."

In future, you may find some of these tips help you avoid provoking an unwanted response.
There are lies, damned lies, statistics - and ADC/DAC specs.

When I read the thread title, I pictured the "Ass to Ass" scene from Requiem for a Dream, only with transformers. Reading the thread left me disappointed and unfulfilled.
Any sufficiently advanced technology is indistinguishable from magic; e.g., Cheez Whiz, Hot Dogs and RF.
