That can cause no vertical sweep. It won't affect horizontal current. Can you get any kind of high voltage with the drive at minimum?
Have you tried disconnecting the HV rectifier tube cap (make sure the set is off) and checking the current draw on the horizontal output stage when turned back on? One note! Be careful doing this as it will want to arc to anything close to the cap lead and will get your attention in a bad way if it whacks you. A shorted HV rectifier can cause excessive horizontal output current also.

Reason: more warning needed!
