Tek 7613
After sitting unused for quite a while, the traces of my Tek 7613 scope are
skewed. AFAICS this is not a front panel adjustment, unless I'm blind. And, sorry, no manual :-( Anybody know where to find the "trace-rotation/trace-alignment" pot? Thanks, Jan. |

It's been a long time since I worked on Tek scopes - if it's not on the front panel, then it might have been located on the storage board; that would be the large circuit board on the right side of the scope, next to the CRT. Pop the covers and snoop around; as I recall, it was a two wire connector (black and red wires) that went to the trace rotation coil. Hope this helps, Bob. |

On the right rear side of the scope,on the top,is a narrow PCB,that is the Z-axis amp and related CRT (geom,astig,T-rot)adjustments.IIRC,the pot you want is labelled. -- Jim Yanik jyanik-at-kua.net |

I have found the trace rotation pot on the Z-axis board.
Possibly the 7613 found it's successor in the 7623 because of the difficult access of the relevant pot. There's no cover hole to access T-rot. But, it is labeled indeed... , P1170... like all the pot's on the Z-axis board are numbered. Anyway, traces are fine now, flat like the Dutch horizon :-) Thanks everybody for helping out!
