One last tweak: Had to tune the modulator's 4.5MHz FM sound subcarrier frequency. It was a little off, which caused visible beats with the chroma subcarrier (I made it switchable: color or B&W). Now it works well.

Looks like the best improvemsnts came from using a dedicated voltage regulator, tuning the subcarrier, using well shielded audio and video lines.
