Monitor deflection magnets; what to do when one falls out & breaks?

these are indeed magnets and were usually the dirt cheap variety. They were set in place at the factory to "trim" the beam to overcome mechanical deviations in the gun and deflection assemblies internal to the crt. They were not all that powerful. The best source of replacement would be another old monitor that you can take the magnets out of. best regards, Steve Thatcher -----Original Message----- From: Brad Parker <brad(a)heeltoe.com> Sent: Jul 15, 2004 11:54 AM To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> Subject: Re: Monitor deflection magnets; what to do when one falls out & breaks?

(I would think a ferrite core would have wires wrapped around it) These magnets are not connected to the wired internal yoke assembly - they are glued to a "collar" which is close to the back of the tube. The collar is round but the magnets are glued to make a square - I assume this helps make the image square. (or not :-) The magnets on the two sides are symmetric as are the top and bottom. Both top and sides have two "tube magnets" but ared spaced slightly differently. The sides have two magnets side by side with no gap. The top and bottom have two magnets side by side with a a 1/4" gap. I can see where the glue was holding the magnet. That's where I put it back. I assume the poles should be aligned, i.e. the poles of the two magnets should be the same, producing a larger overall field (I presume) Well, it fell out onto the floor when I took the enclosure off :-) -brad
