That's probably just some errant, wandering ions that haven't yet been captured by the getter or have broken loose covering the cathode. Anyone of you got Peter Keller's book about CRT's? Raymond

I advise against such harsh measures at this time. Why not go ahead and first try another simple-to-do thing that several contributors, including myself, have recommended many times, again during the

I think that in places that are subjected to the most stringent safety regulations, like kitchen and bathroom, the mains connections have been renewed and set up according to the modern system,

Go to x-y mode. Can you make the dot nice and small by adjusting the focus and astig? Does the dot continue to look good as you move it up and down, and left and right? Sent from my iThing, so please

First time poster here. I’ve been reading many posts and learned a lot from you guys. I got a 465B from eBay and I’m having a problem with getting the trace to focus properly. Even after checking

I can’t seem to be able tonpinpoint the location of the X cap in the manual. So as to save me some time, anyone knows which one it is?

Hi, forgot to add: in the Netherlands, Germany en Spain, they use wall sockets in a originally German model, meaning you can plug in both ways. Devices are supposed to be designed so there is no

Interesting, I can't explain why this would be. For giggles try and plug the scope into the bathroom outlet and see whether the noise goes away?

Hi Steven, Very interesting and thoughtful approach. Will definitely test that as well. Thank you.

What I meant is that I tested all the sockets in the house, with several extended cables, against this pipe and the ground lug in the bathroom, and they are ALL properly grounded. They all pass the

Hi, All - this has been an interesting thread, but no resolution (yet). I am neither an EE nor licensed in EU or Europe voltages. While I don’t have any 465B or 466 scopes, I have several 2445 sets
