No crosstalk at all?[/quote]
I wanted to really do a serious check before answering you, that's the reason why I've been so long:
NO CROSSTALK ! :grin:
At least, if there's some crasstalk it's under the noise floor, so it's impossible to hear it or to see it with a spectrum analyser...
I tryed to have the maximum distances between the transfos and I put a mu metal shield on them... That's one part of the reason, the other is maybe in the way I build the power supply. I left on the boards all the regulators and I build a separate power supply with a diode bridge and two 10000µF caps. So DC current in and separate regulation on each board...
