Obviously, it was aimed in part at you, but you are not
alone. You weren't the first to criticize my rehab
methods so I thought it unfair to single you out.
Perhaps it was chickenshit not to address you directly.
Your comments were just the trigger.

Of course your advice is valued, extremely so, and my
separate thanks for it was sincere. That advice did
come, however, with a morsel of baggage. Consider, for
a moment, your statement to me that you "have a major
objection to 'whacking' anything near a CRT." Stipped
to the essential message, it is excellent cautionary
advice. The phrasing, however, and particularly the
inclusion of "major objection," turns it into
criticism. You could have said "I would be careful
about 'whacking" anything near a CRT." Same advice; no
criticism. (So, call me sensitive.)
I think I understand the dangers of CRT implosion, and
I tried to be careful. Placing a chisel firmly against
the side of a brass washer on the outside of a heavy
metal frame in which the CRT sits, well to the rear of
the CRT, and then 'whacking" it with a hammer while
bracing the unit, did not, in my view, imperil the CRT.
The force was narrowly contained. Blame my imprecise
description, which probably made it sound like I was
taking wild hammer swings near the display.

Not identical, as inicated separately, but I assume

I thought of this initially. The reason I didn't is
because the yokes were glued on and the wiring from the
yokes was soldered to the boards. Would have been a
lot of effort. Granted, it is probably something I
will now have to do in any case.

That is where I am at now. However, I still intend to
do this, at this juncture, at the macro level by
swapping the video boards.

That's right. I have the maintenance manuals. The
solution given for every problem that cannot be solved
by tweaking or moving the yoke is to replace the entire
unit.

I will, and I hope you'll keep providing useful advice.

It did here, but also bear in mind that some of us are
simply do not have the tools and knowledge to repair
things at the component level -- yet.
