Hi!
First of all, I want to apologize for my English, mostly through google translate.
I have no experience at all in repairing oscilloscopes, so I have a lot of experience in the opinion of some specialists.
It is about an old oscilloscope, KIKUSUI 555, hybrid, transistors-lamps, which I received and which I managed to put into operation with the help of clay1905 who is active on this forum and who put me at he provided the electrical diagrams, for which I thank him very much once again.
There is still one problem to be solved. The signal trace is inclined to the horizontal and does not line up with the measurement grid. I am adding a picture.
The trace remains in a straight line in any position, up, center or down, but inclined at about 10 degrees. The CTR is 5UP1F or 5UP7F (from the operating manual). I did not remove the tube from its support to rotate it until I run out all electrical trace rotation attempts.
I really need a professional advice on what I could do to align the trace horizontally with the measuring grid.
Please, can someone help me?
Thank you in advance
PS
If you need the electrical diagrams, please let me know!
