Hi, I started to repair a HP 130A scope in Milano, Italy, and I am presently trying to extract the CRT from the case.
The manual says

I am not succeeding in "loosing the CRT base from the socket" and I am worried to brake it.
Does anybody of you have any experience in doing it?
Another issue I am having is that I see small inconsistencies between the manual (serial 125) I got from the HP repository and reality ( serial 2482) . For example V20 is a 6BQ7A on the tube replacement chart but a 12AU7 in reality and as printed on the scope frame. Any newer manual around?
I am interested practically in any non trivial info concerning my project, thanks to all, Pepi
