Transformers usually don't effect the frequency in the vertical. It's usually capacitors and resistors that set vertical frequency. First check your work, it's rather easy to install a capacitor 10x or 1/10 the original value and that'll mess up frequency something fierce. If the caps are correct next check resistors measure within tolerance (probably 10% in a set like yours) and if higher than rater tolerance change them, if lower suspect a parallel resistance path and unhook one leg of the part to verify.....
If all that fails you can decade box engineer a new resistance or capacitance value to get correct frequency.

Back in highschool on my first TV restoration I moved cross country after the first recap and before I fixed a video issue. When I finally got video I had vertical like yours, the original bumblebee caps (didn't know how to read them back then and recapped off the Sam's manual) had been tossed months ago and I discovered that one vertical cap in the Sam's parts list was 10x what it was on the Sam's schematic (Sam's typos strike again)...I had no capacitors or money, but I had a bag of resistors from scrapped gear, and a decade box...I played around with raising and lowering various resistances until I found something that worked.
