It's different than a shunt regulator though, since a HV shunt absorbs whatever voltage the CRT doesn't use to keep a constant load on the ultor supply. The pulse reg is different, because it modulates the input power to the flyback so theoretically the flyback should stay cooler if the demand on it (beam current) is low. In other words, the way I understand it if the HV needs to be lower, then voltage is shunted out of the primary. Seems that would be a lot less harsh on the fly than running it balls to the wall all the time.
