As I was swapping parts from one flyback to the other, I decided to put a meter across the focus rectifier to check it. According to the meter, this one is open (checking it in both directions). For the hell of it, I pulled the focus rectifier from my spare 15 chassis, and it gave me an open reading as well. Hmmm... being that these are so large, will they not check on a meter in the same manner as a modern diode?

As I recall from some time ago, seems I remember checking the focus voltage a while back and it was within specs. However, when running this chassis in a set, the picture was a little fuzzy. At the time, I had blamed the fuzziness on the 21FJP's safety glass being completely delaminated all across the face of the crt.

I am going to go ahead and re-install the old one because I do recall checking the focus voltage before and it was good.

If it turns out that i do need to replace this, what do i need to get? Sams has a listing for the original part number, but no measured current. I am going to assume that this is not something I can go grab off the shelf at the Rat Shack.
