Helllo.
So i recently got a hold of an analog Hameg 203-4 Oscilloscope. After testing it, every functions and values are correct. However, the trace line isn't centered on the Y-axis. Even though the "Y-pos" knob is turned all the way anti clockwise. When the "Y-pos" knob is turend all the way to the left, the trace line rest on the line above the center line. And when turned all the way to the rigth, the traceline dissapear. As if it goes above the screen (this aplpies tp CH 1 and 2).
The handle on the oscilloscope is a little bent, so maybe someone previously has bumped into it or dropped it (no visual damage though). Thus setting the CRT (or inner components) out of dissalaiment. So I am wondering if this is the problem. If so, does anyone know of a way (if possible) to re-allign it? Or other suggetions on how to change the trace line.
(see attachments for pictures of the trace line and the possistion of the "Y-pos" knob)
