Thank you very much! Love your tubetube chan. The part that confuses me is in picture "cr70-02.JPG" Simplified Test instructions. It says reset Individual gun setup switches for each gun of a color CRT after performing Shorts, Cutoff, and emission tests. I'm not sure what it means by "reset Individual gun setup switches for each gun of a color CRT". Do I put all of the switches back to 1? In my manual it also says the same but on another page it says something along the lines of making sure before changes are made to not have it on the emission test when making a change or else it will only replace the last emission test thus not getting the right readings and the tracking test will be inaccurate. So where do you turn it to after doing an emission test of the red gun before I make the changes on "K" and the color gun knob? I have looked everywhere for months on someone using this tester on a color CRT but no one seems to be sure if they are doing it right either. Even with the universal adapter on color crt's. Only video I have found is yours and you are using it on a B&W tube which you don't have to change the guns. Of course you just have to keep it on red/B&W. As you can see they are lacking details when it comes to color CRT testing and which knobs to turn where before doing what.

I understand part 2 of that section which is saying to test every color gun before using the tracking test to compare all 2 guns. If you have a color CRT around give it a try and you will see what I mean when I say it's confusing.

Thanks so much for the reply!

I have uploaded the pictures of the manual in question.
