On going Zenith 25MC33 roundy restoration

[Electronic M]

As promised here are the pictures of the lin coil on my set.




I subbed in my spare Zenith 21FJP22A today.



About 2 years ago this tube was the first tube of any type which I successfully removed the cataract on. I decided to do the swap the lazy way...Pull the chassis, neck hardware, and degauss frame(I put the set face down for this part) then loosen the adjustable tension band and lift the old CRT out. I then dropped the new CRT in, loosened the screws which connect the CRT mount hardware to the mask, tightened the band snug, tightened the screws back up then tightened the band a pinch more.




All that is left is to set up the neck hardware for the new tube before I can work on the electronics again.

Thanks for the pics Tom. From the looks of that coil, it has been broken at some point in the past and someone melted it back together. I would think that as long as the spooling area is not broken or collapsed, the conductor wind is continuous, and the shaft is free then everything should be OK with one of these. Mine felt springy at the wound area which would be a problem. I need to double check that to be certain. I have never pulled the chassis as I am trying to wait until I get all the caps that I need. Again, thanks and good luck with your set.
