I wouldn’t bother building a mains filter. Aside from the danger if you do it wrong or someone else comes across your creation, you can buy perfectly good ones integrated into IEC sockets or standalone for series wiring for 5-10 on RS. A decent set of X-Y capacitors and a common mode transformer is going to cost at least the same.

The main thing with the IEC ones is they are integrated into the chassis which means there is no opportunity for the noise to get in (or out!) before it gets into the device. The trailing lead variety isn’t quite as good.

Look for RS part number 2192785 for example.

Also don’t forget to replace your X class capacitors every decade or so. They are consumables and like to catch fire (I had a non RIFA one go the other day)

RIFA in my B&O 8802 filled the lounge with a delightful cloud just before Christmas, not bad for 36 years old though and the stench got the kids out of there for a couple of days

It's worth taking a look at Surplectronics website. I got some IEC filters very cheap.

Blimey. I think every sentence in that post held something I'd never heard of. I'll get me coat. 🙄

Seriously, a very well composed post. I'm not being sarcy.
