Always some resistance don't meet.As the yoke is not operated with direct current, isn't the impedance more relevant than the resistance? I would measure the impedance at the typical frequency for the respective coil (50Hz / 15,6kHz) and use that measurement for comparison. By theory, if the size of the tube and the angle of deflection are equal, you should be able to swap the yoke, as the electrons don't care about the model, they care about the physics, which would be presumably equal then. As a rule of thumb, if the new yoke sits well on the tube, I would give it a try. But there is still the risk of electical incompatibility - such a modified monitor should not be operated unattended due to the risk of fire, you know. I will take no resposibility if you do that swap trick. Btw: I would not try a yoke from manufacturers who are known to implement their own standards, like Sony for instance.
