I have two 2467B scopes on of which I'm using almost daily and they both
are as good as new as far as CRT concerned. It has some tricks to protect
the CRT from burnout -- it turns the beam off after sitting idle for a while
and also has interesting feature that made me think they are defective at
first :) Unlike 2465B its readout jumps within readout area at random
intervals (maybe periodic -- didn't measure it) so it doesn't stay in the
same place all time and thus doesn't burn itself into MCP.
7104 is older and its MCP protection is simpler and quite annoying at times.
And one thing about that video -- do _NOT_ do what they did in it. Never
ever if you want it to last. Setting it to brightness THAT high will kill
your CRT in no time. There is absolutely no reason to crank brightness THAT
high on 2467B -- trace will be very thick and it won't do any good for faint
traces.
Repeat after me: think twice about what a youtube video tells you to
do.
Do that again.
then don't do it.
I'm treating the CRT as one that I can't easily replace, let alone
adjust properly. You ever look at all the adjustments on that thing?
