I will post some more pictures when i'm at home.
I won't fix the scope, the HV board is a bit expensive but not so hard to find and the CRT is more expensive.
It sucks because I was given this scope by my employer who upgraded to digital scopes, there was no other 2455 so they did not keep it for spare parts, i had the opportunity to take it home. My employer was happy that I could finally practice electronic diagnostic even though it's not my job
I had it for a long time, I used it to fix my electronics and also learned how to use scopes with this one by doing all kind of stuff on it.
If I had enough money I think i'd repair it but I think i'll save up some money and upgrade to either, digital scope or analogic memory scope.
Just so you guys know, i'm a noobie in electronics, i'd rather have a smaller scope at home than a 2455, even tho I loved it alot :'(
