I looked up both flyback numbers in my Thordarson cross reference and while 55C113 crosses to a Fly 1, there is no listing for a 55H11S? Does your flyback even resemble the one pictured in Phil's restoration pictures? I'm a little suspicious that that number could be a much later part, possibly not a direct replacement. On the other hand if it looks like a typical Fly 1 it probably an OK sub. My newest cross reference no longer included Hallicrafters so I have no way to verify when a 55H11S may have come into existence.
