A 3 henry choke at 120 hertz has a reactance of about 2300 ohms. The same choke at 10 to 20 kilohertz, the region where hash likely is, will have a reactance of:Xc=2PiFL=6.28x10 000x3=188400
A whopping 188 Kilohms!, How the heck can hash get past that
By capacitive coupling.
But I agree, with proper layout and perhaps throw in an extra small choke for filtering it should be possible to get rid of the noise. If it's possible with a transformer (as claimed) than it should be possible with a filter as well.
