I would say yes. As long as not removing the rubber anode cup, the tube connector on the end and/yoke can be removed without discharging the tube. I had removed/swapped around several early Mac tubes without discharging the monitor. On Thu, Feb 8, 2018 at 8:51 AM corey cohen <coreyvcf@gmail.com> wrote:
Ok. Well then let me ask you and Ian this..
Can I safely disconnect the plug at the end of the CRT neck without discharging?
That would make it easier to take the tube out while the anode wire is still connected and then in can discharge the tube with a screwdriver.
Also is the best place to clip onto the implosion bracket since the ADM doesn’t really have a metal chassis?
Thanks, Corey

I’ve done the screwdriver trick myself. Because often, even after waiting a few weeks, there can still be enough voltage to make your hair stand on end. LOL

I don't remember any particular trick or real difficulty in doing it.
Maybe you needed to get the tube loose to get the screwdriver in
there? But I thought it would fit in there without too much problem. I
know I've done it a whole bunch of times and nothing sticks out at me
as being out of the ordinary about working on the 3A. Remember you
don't need to disconnect the anode connection right away, just
discharge it.
If you're doing a lot of work on one of those monitors, sometimes you
do need to get a bit creative though:

So I was about to swap out my ADM5 for my ADM3a with my ALTAIR and
realized while I did replace the electrolytic and tantalum caps on the main
board, I didn’t change the electrolytic caps on the analog board behind the
tube.
No big deal except that the rubber cup is on the top where I can’t get
to it without removing the tube and you aren’t really supposed to remove
the tube till you discharge it under the rubber cup. So chicken or the
egg?
Or am I just supposed to let the ADM sit unplugged for a few weeks and
just assume it self discharged?
Just when I thought I was finished with this project and was going to
move onto my TI silent rebuild.
Thanks,
Cheers,
