Horizontal Width Coil - Ferrite Core Question
« on: August 02, 2006, 08:54:22 pm »
I am having problems adjusting the the horizontal width on my 19K4901.  I removed the coil and ordered a new one.  Now that I have it removed I can see through the coil, I am assuming that the ferrite core has been destroyed?  In other words if the core is in-tack I should not be able to see through it(top to bottom)?

Thanks,

Jimmy

Most width coils you can see all the way thru the hex shaped hole in the slug.

So the ferrite core is really a cylinder inside the plastic tube?  Once I got it out pieces of the core fell out, but I can still see the cylinder.  Even once I got it out I still could not get it to turn... Hopefully the new one will turn with ease...  The monitors mfg date was 1982.

For some reason, Wells-Gardner glued the slugs in place on many monitor models. The replacement width coils you buy today are not glued (thank goodness).

Thanks for all the good info Ken!  I should get the replacement early next week.

Be sure to use a plastic hex tool on those also....regular metal allen wrenches and scredrivers tend to chip and crack the ferrite core. (guilty)

Radio Shack (ugh) generally has a $5.00 set of "TV" tools that work well on most.

Yeah... I got the ones from Radio Shack....  But I think the guy before me didn't...  :hissy:

Oh, I indeed know what you mean there......  :angry:
It only took one time for me to learn the hard way.
But you would be surprised how many times I've come across one that is already broke when I work on a used machine.
