Anyone knowing the Tek 2445B scope? I have one which is exposing a defect. The logic seems to be functioning. Only there is no beam. Not sure whether it might be the HV supply or sth. else. I got a circuit diagram. Anyone some old "Teknichian" who might be familar with this instrument series and be able to pinpoint the most possible fault or some first checks to narrow down that fault cause. -- Christoph
There is diagnostic diagram 8a decision tree diagram) in the rear part of the service manual. Did you follow the instructions mentioned there? And if yes, how far did you proceed?

It doesn't seem to take the calibration...
