Monitor deflection magnets; what to do when one falls out & breaks? - test-drb@ccmp.vtda.org

Hi
 It should be noted that when broken, these cheap
magnets will lose some of their magnetism that can
not be recovered by simply gluing the piece together.
 As was mentioned, finding others on scrap units is
the easiest. Positioning these is an art. They never
seem to do what one expects so take your time at
locating the best location and orientation. It most
likely will not be the same as it was originally.
 Watch out for the anode lead and wear eye protection,
any time you are working on he monitor with the cover
off.

   These are cylindrical, low-gauss ferrite magnets called 'trimming 
magnets' or 'pincushion magnets'.  A lot of cheaper CRT devices use 'em to

tweak the display.  They're a pain in the butt, especially the ones near 
the front of the CRT that gradually get demagnetized with each power-on 
degauss cycle.

   They are sometimes available at larger 'real' hardware stores (in the 
US) like True Value, etc.

   Or, as was wisely suggested, cannibalize them from another junk tube.
