Swap is super easy so long as the donor tube has a compatible yoke and the yoke uses the same connector. Also note that some degaussing coils are not compatible with certain chassis. Keep the original if possible.
Swap tube: 10 minutes including discharge, unbolt, rebolt.
Swap deguass coil or convert coil connector if necessary: 5 mins
Swap yoke connector if necessary: 5 minutes
This is all it takes to 'create' a new monitor out of a donor TV and a Wei-Ya or Jen-Shin chassis provided you find the right yoke match on the donor tube.
Now if you need to swap the yoke, add a large amount of time to mark convergence rings, remove and mount a new yoke, get a pattern generator (specific device or boot screens from various boards) and start your aligning process. You may need to move, remove or add metal deflection bending tabs between the yoke and the tube as well.
Then onto convergence. You might get lucky or you might end up being so far off with the new yoke you'll need to start from scratch. Good luck is all I can say. It isn't fun without the right equipment. Some times no matter how long you spend you just cannot get the tube to reconverge due to a core difference in the shape of the tube as compared with the original. The tube + yoke + rings make the combination work. Pulling off the donor yoke and putting on the arcade chassis yoke may mean you just can never reach perfect convergence again.
In many cases it's just easier to buy a chassis known to work with a specific series of donor tubes with attached yokes and not deal with trying to swap a yoke and converge. I don't know about others, but a $40 used or $70 new specific chassis off ebay and a free tube = 20 minutes of swap time is a lot better than wasting hours trying to swap yokes and converge a tube.
I've only had 1 good K4600 + yoke swap, and one 'close convergence' K4900 + yoke swap. GO7 just has never worked for me. And in all 3 cases, donor TV tubes with compatible yokes have been hard to find, since most are 15 ohm vertical resistance while a K4600 is 8, and a K4900 is 48 and a G07 is 55 ohm. That's why it's easier to just buy the replacement chassis and pay myself to not waste hours trying to converge -- And then I end up with a brand-new looking sharp, and converged as well as the TV was image as a bonus. But then again I'm not a tv tech with great equipment.
