Yes, or make them worse. The low voltages off the flyback are proportional to the HV winding, so changing anything on the primary side affects them.

There might be a way to get a bit more width without sacrificing HV. On tube TVs we used to add a capacitor to the damper circuit. I'll ask my older brother - he's a lot brighter than I am on this stuff. There are a bunch of guys here who know a lot more about this than I do, hopefully they'll see it and chime in.

We used to do stuff like this back when TVs were a lot more money and worth the time, but when done as a hobby, the time is often diversionary and fun.

If you can get the sweep close enough and the HV is within reason, the lower secondary voltages can be fudged a lot easier or even subbed from another area, particularly if it's a low current source.
