Hi Jon,

Thanks for your reply.
I already downloaded a manual, without it’s impossible to do any repairs.
I will check your suggestions, I also noticed that as soon as the picture is unstable in terms of astigmatism, the voltage on the grid remains the same. Also, the picture is sometimes sharp at 30V and sometimes at almost zero.

Anyway, tomorrow is another day.

Thanks,

Wilfred
