I looked up TV-107. It is listed as a convertor transformer with the sound take off similar to the RCA transformer. It was likely used on full split sound sets with sound take off at the convertor. One thing I feel is the trap of the origial spread out on the bakelite frame will have a higher Q. It means that the trap in the RCA provides a deeper null. This may be important when adjust the bandwidth with the 22.1 marker. It means that you may need to modify the alignment procedure to narrow the video IF bandwidth slightly to reduce sufficiently audio carrier passing the remaining video IF stages. Although there is a second 21.25 MHz trap down stream. It is a flip.
It can be made to work but I would prefer the originality.
