Any time I've tried it, one goes bad and I end up replacing it later. For instance, two nights ago I pulled out my restored '61 blue Zenith 19" tabletop with original filters and after about an hour the vertical started stretching and then lost lock. A section of a cap that tested good last year went bad and now I have to pull it apart again. Thank you Zenith engineers for the "service saver" panel, at least I don't have to take the whole thing apart again.
