Positioning question

[Dxvideo]

Hi all,

Last month I made two lateral MOSFET amplifier (2SK1058+2SJ162). And at the moment I am putting them in an enclosure. For WAFactor I must put them in the same enclosure with the transformer.

As your experiences which is the best position to reduce noise.

Or any more position you imagine.. Pls.

Hi

I would think keeping the changing flux from the transformer as far as possible to the higher impeadance input circuitry would be best, keeping in mind the shape of the flux around a toroid.

Just use another transformer with lowered inductance (down to 1.0-1.2 Tesla). An inappropriate transformer kills all other excellent design intentions
