Hi Morzh,

Dunno if the AC EMI caps are an issue. I never liked the concept but never had an issue with these causing an issue when looking only at the radio. Hopkins filters used on commercial electronic equipment have the same caps but also inductive filters.
Modern TVs use the same concept. When adding an external input that is at ground potential (grounded chassis), that would be a different issue, as there would be current on the shield.

"Do Justly, love Mercy and walk humbly with your God"- Micah 6:8
"Let us begin to do good"- St. Francis

Best Regards,
