Not directly. We model a fair bit because real world variables are so high we can't really account for measuring in one setting being accurate for multiple settings.

Also we listen. A lot of filters sound horrible IMO. They measure ok on a 50-50ohm setting but that isn't very real world. They also don't account for resonances very often.

Hmmmm ok...
Different question.. Wuerth has common mode chokes too... Especially flat ones.... From the values would one of these be suitable?

Can you post a link?

If the key specs check out and PCB pin layout works, why not?

A link would be good. From the description alone it sounds like differential mode for a car, which really only works at DC or in minor, minor amounts that have to be controlled carefully.

All of those could work, used on the fuse. They don’t offer any differential filtering like the Comocos though. But the pin spacing if probably off (I’m on phone, hard to check).

The same wattage type values would apply just fine, too.

Hi Destroyer, I bought a few of these from a local surplus supplier and use them in all my amps.

Is there any benefit in using your pcb or are they similar performance?

thanks.

The Fo-Felix with any given CMC is higher filtration. Also the M5 is the only one in that PDF without Y caps, that often are a determent to sound with single ended operations.

I suspect those are better than the IEC inlet filters that sound awful.
