Well, I have discovered that the choke is probably the issue after all. Why, because what I thought was a new Stancor C-1709 does not measure, resistance or inductance, as is should. So some other type of new choke was in the box. I probably should have verified its inductance before I used it, so lesson learned here. And, as Morzh pointed out, even if it was the correct choke in the box, the C-1709 is too small. So, I'm going to search for a choke with specs as close to the Philco part as possible, and add a resistor in series if needed.
