I need to substitute the PSU for my Magni Heresy (15V AC 1.5 A) but on Amazon et similia i can't find a single one that outputs AC, from the Schiit site I can buy it but is like 16 euros for the product and 40 for the worst shipping method.

Is needing an AC psu this niche?

Any suggestion on what to put as key words in the Amazon research or another site where I can search, sorry for the off-topic but I don't know were else to ask

If you search Google for
15V AC 1.5 A -dc
Putting the -dc will really cut down irrelevant results. I see a bunch. It'll probably get you a more local shipper in Google shopping for your location.

It's probably just a transformer. They are not as common as 15V DC SMPS but I do find matches when I search google. BTW, the Topping L50 also comes with a 15V AC PSU i.e. a 15V transformer in a plug pack.

Not just niche, but possibly not even legal any more - they generally fail the standby power requirements in the current EU ecodesign guideline by a substantial margin. My Atom Amp+ mains AC supply draws almost 3 W all by itself doing absolutely nothing.

Apparently high efficiency transformer design is a thing (if a bit of a black art) but generally diametrally opposed to how mains power supplies tend to be procured. A bit of core saturation at nominal voltage is often accepted as a means to reduce the number of primary turns alongside resistance and hence increase VA capability. Magnetizing current also seems to be increasingly an issue in very small transformers.

Good point. It was something I had not thought.

better to look on ebay for a AC voltage transformer and buy something good grade R-core type
I bought one for my Topping L30 very nice for not big money but EI type
