Back in my engineering old days, we used to calculate magnetic flux losses etc.

Indeed the "donut" looks close and big... but it could work. It has to, you have it already LOL! What I would have done back then though, to get the best chances, is rotating it so that the cable / output faces exactly in the opposite direction of the most senstive parts.

I don't know if that still makes sense nowadays, but back then the part where the field radiated the most ("escaped somewhat") was at the cables output... so one would have wanted that part farthest away and facing in the opposite direction.

Just an idea...

Ah yes. Good advice. Mighty ZM shed light upon us! [emoji1317]

(Could have been a good joke, too... I shall use a used thuna-can, as somebody once recommended. Gnihihi.)

No seriously, I‘ll check it out and if it’s a problem, I‘ll either can the donut or make an external psu with lumbo-... mumbolical wire and use the free space for a dac[emoji4] ... many months later.
 
I didn‘t spilt it. Because I was thinking of it after soldering the popularion. Since I hadn‘t the right tools to clamp it without crushing the parts, I decided (twice) to leave it as it is.

It‘s still not finished, but almostalmost! Sssiigh [emoji849]
