The 1st AF does not draw much current, so the open primary shouldn't cause a great increase in voltage.
Did you recap this radio and use higher capacity caps? What is the B+ that you are getting vs te specs? One other issue is that a lot of these radios were designed for 110V, and the average outlet voltage nowadays is 120V., so about 8% or so high.
If the secondary of the interstage transformer is good, Ron's "bridging technique" should work great. I have a Philco 20 with a good transformer, but I am going to attempt to RC couple that one.
