There is a way to evaluate the CRT. You can use an old TV tube tester and make sure the pins are correct for the tester. Usually these testers are cheap and come with several adaptors for different pin outs. They also can have a booster function that burns off the tube a bit. I don't know if this would work or not. TV pic tube testers are cheap. I just gave away a nice one to someone who works on old scopes and I do have access to 2-3 other units
What tube does the 141 use??? Not sure about the 141.. I have an original US WWII unused CRT that was used in lots of scopes (Box sez EICO, but Heath and others used the tube)
Tube is free but I do not think it would ship well.
