[Johnson] Johson Screen Supply Choke

[Tom Elmore]

Can someone please explain to me how the choke in the screen operates in regards to AM operation? When
operating AM with say my Viking desk kilowatt is the choke in the screen supply in addition to providing voltage regulation, blocking audio from getting back into the screen supply? When audio is applied to the plate of the final (4-400) from the modulation transformer does it appear on the screens at the same time?
