Been working on a home improvement project so not much progress but I did pick up a Sencore CR70 and was able to test the 2 CRTs I have. Both are Packard Bell labeled 25xp22 which makes me think they are original to the TVs.
Naturally the tube in my project TV has no cataract or discoloration but measured almost no cutoff on red or green and barely any for blue. Emission is very poor for red, marginal on green, and fair on blue.
Now the CRT out of the large parts console I picked up measures good all around but it is quite discolored under the safety glass. I have watched shango066 pull off the safety glass on several CRTs so I see it is possible. What does everyone think for this one? Also let me know if anyone has a CRT they want to sell and ship to me (I will post a separate thread in the classified section).
