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
Alan, GI0OTC
