I am getting snow on the screen and it changes with turning the dial.
I would like to make a test adapter if someone could help me out with that. This way I can tell if the guns are infact weak.

OK, you've got a raster. From what you're saying, there's a high probability it's got a weak tube. For the service line, the "screen controls" (I called them G2 in my last post) should give you a red, green, and blue line. White is most likely the green and blue superimposed. Normal procedure is to advance them until they light, then back off until they just extinguish. If you didn't see red, the red gun might be very weak.
Best thing to do if everything else seem good and there's no smell of something getting hot (btw, check the filter cans - none of them should be much more than room temp) then let her run a few hours. If the TV hasn't been run in 20 years it might pick up emission.
Regarding a tester, you can make a universal adapter using color coded clip leads that will work on any tube. I did this on my B&K 467 during the last of the RPTV years when I kept running into new projection tubes and B&K no longer supporting the 467.
What kind of CRT machine do you have?
EDIT: oops, didn't see you had a 465.. Those adapters are fairly easy to find and cheap enough, but while the 465 is a good tester, it's *brutal* on the tube for any restore functions.
