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
If you're doing a lot of work on one of those monitors, sometimes you
do need to get a bit creative though:
