From my research, 1st one is to a 20 Inch Tube, the other is to s 25 Inch Tube. I bet the Internal Capacitor is different on the 2....I summize that the Cap on the larger set dont need to be a higher value than the smaller one, since I guess larger CRTs are basicly bigger capacitors. So maybe if you used the 25 inch FBT in the 20 Inch it would be ok, but Vise Versa would be questionable. Just a theory from what I can summize about my experiences with Flyback Failures. The internal Cap in the FBT has to be within a Certain Range for the CRT size I think....again just a theory.
