A bit of a minor update. I recently acquired my first CRT tester. It is a Sencore CR 161. From what I have heard online, Sencore is a trustworthy brand. After reading the instructions and manual, I quickly learned how to use the tester and began using it to test all the CRT's I have.
The one in this motorola tv is supposed to be 6.3 volts and hi bias mode. At this voltage red and green color guns were good. Blue however was on the weak side. However at 7.3 volts which would simulate what a tube brightener would do to the emissions, emissions improved for all three guns notably, and blue went solidly into the good territory.
No shorts were found for this CRT which is good to know.
While this CRT has many hours on it, I am a bit surprised that emissions seemed higher than I would have guessed based on the alleged history and heavy use of this tv over the decades (barber shop tv). I was fairly impressed.
