Yeah...way to go on this one. On these electrostatic focus tubes, I don't have anything to go on to judge quality other than the brightness of the picture and the fact that it's not the original, it's an RCA 7JP4 and bright. N way to test on my Sencore CRT tester. No matter at this point. I've got a ballast to build. I can check the CRT voltages once that's done...as long as I know what pins are HV.
