As I peruse the 70 and 90 diagrams I see that the hv current is split. Most of it is handled by the filter choke and only a small amount is being drawn thru the field coil. It's feeding the plate of the 1st audio and the sg's of the rf if stages and the osc plate. The output stage, rf and IF plate current comes from the filter choke before the field coil so the current rating of the fc is going to be about out 30ma or so.
