So you think the tube is at his end?

That's an interesting suggestion, worth trying, Claudio!
So far how much viewing time do you have after the filament voltage
increase?
...and what did you do to increase the filament voltage?
Thanks,
Greg

Hi Bas
I apologize for my bad English
It seems that the crt tube is perfect to run out, I got good results by
increasing the filament voltage of 1V, 1 .5V

Yes, true Greg, with very low intensity, focus is good.

Bas,
Does the on-screen grid sharpen-up when you turn-down the intensity
control? (The signal trace might not be visible at this lower intensity
setting, for purposes of this test.)

Hi All,
I have a HP-85662A display unit with problems. Just the on-screen grid is
very unfocussed as if it is written twice with time difference.
It looks like it is just the grid not the signal, signal is good as it
seems and can be focussed.
Any thoughts, drop me a line!
Bas
