Yes the Hammond should be fine, although I don't know if you really need one as big as the 125E. The PP '45 output stage only puts a max power of about 4 Watts, which is a lot less than the 15 W rating of the 125E. Perhaps more important is the physical size and what will match the existing mounting holes. I would check out the 125C or 125D.
As long as you can choose a turns ratio that will give the proper impedance transformation from 0.7 ohm to about 6700 ohms you will be fine. The exact match is not all that critical, and anything from about 5000 ohms to 9000 ohms should work fine.
