I own a 2465 which exhibited non-linear vertical traces for Ch1 and Ch 2.
I traced the problem to failed -8 Volts from the LVPS. In particular, 1101.
I recapped and all was well. Still using the scope.
Thanks for that info, Mac. I based my response on what I remember of the (all too frequent) messages of vertical compression, from the middle increasing towards the top of the screen, for channels 1 and 2 only, as seen on this forum.
Did I miss your issue here?
