It looks like the tube has a factory defect where they failed to weld the
pin 5 lead to the strap going to the astig element. I wonder if there is any way
to externally weld it? Induction welding, laser, other? I can't use high voltage
as there is no access to the element. I attached a picture showing the fault. If
I tap the tube, the screen comes into focus. I verified all the connections
externally.
?
Next question,
?
Somewhere I read that a tube from a 2215A would work. However, that tube
uses a mesh electrode whereas the 2232 tube does not. The only difference that I
can see is they connect the mesh (pin 12) to a -100 volt supply.
?
I need to find a junker 2232 with a good tube.

Looks like the same tube is used in the following scopes:
2213A, 2215A, 2220, 2230, 2235, 2235L, 2236

I received a 2232 scope with the UPS obligatory damage. Something in
the tube is loose and the display is way out of focus. A very light tap on
the tube seems to cause an internal connection to make and focus comes in
very briefly.
?
Does anyone have a tube for the 2232 scope? Part number 154-0861-00 or
-10
