HP8569B CRT Jitter.


 

Hello all,

The voltage rails are within tolerance except the +158V is little low at 156V and the red LED is showing ok.
There is a slight jitter and the picture width is narrow by about 4mm, the jitter intensity varies with the Scale Inten and Inten controls.
Any pointers appreciated, I have the ARTEK manual with good scans.

Regards

All sorted, just the broken switches to address now.

Alan, GI0OTC?

If i may ask how did you fix the scale intensity jitter ? I'm currently having the same issue with a 8569B.

Thanks,
