I just picked up this "golden oldie".
The only thing not working well is the horizontal or X-shift. The trace cannot be shifted to the right enough to fill the right most 25% of the screen.
So my guess is that the Timebase / X amplifier circuit has an issue.
Only thing so far I checked are the 170V and the +- 20V rails, which are ok.
Any ideas anyone, please?
Check the X amplifier final stage transistors that drive the deflection plates.
Hi Icsaszar; I did and indeed one of the BF258´s is dead.
I´ll replace it and hopefully issue should be gone.
Many thanks for your fast and great advise!
