York Coil Problem - TXN2726 27 TV
The part you want is called a "yoke", and not a "York". This is the electromagnetic coil that fits on to the neck of the CRT, and makes the magnetic field from the scan amplfiers to scan the the beam.
I don't know if you realize that when changing the yoke, the purity and convergence alignment will have to be done on the set. This is a job task that requires skill and a lot of practice. Not many service techs are very good at this type of setup. There are specific calibration patterns used for this type of setup. When changing the yoke, it is very common that the ring magnet assembly (convergenc and purity magnets) that is behind the yoke must also be changed. Some yokes come with this assembly together, depending on the model of yoke.
Some manufactures do not sell the yoke separately from the CRT. When the CRT is replaced, it comes with the yoke and magnetic assembly.
An interesting question would be is, how did you determine that the yoke is actualy bad??? It is extremely rare that this type of part fails.
Parts for CRT type sets are getting very scarce. Because the market for spare parts for CRT sets is decreasing very quickly, the clone part manufactures are also not making the generic type dedicated parts.
A way to have parts for your TV set would be to search for a used set that can be used for spare parts. You will have to hope that the same parts you need are also not defective in the used set.
In my opinion, if the yoke is actualy bad, I would be shopping for a new set rather than go through all this trouble. The LCD TV sets are excellent. There is no way that your CRT set will ever be able to perform like the new LCD sets.
