Hello everyone! I am happy to see that Jeff has rescued that 533A scope! I have one myself, but it's beyond repair sadly to say.? As far as transporting CRT's goes, for the most part, they are a little hardy, but I have transported my 535A many many times back in my younger years and never had a problem. (Had a friend about 40 miles away that was into electronics). As far as aligning CRT's in older Tektronix scopes was rather easy and is in the manual. One part is rotating the CRT until the horizontal trace would be dead on the graticle on the scope, then there is adjusting both vertical and horizontal. Most of my scopes, I have had the CRT out and back in for cleaning.? That would be my 531A, 535A, 545A, 503 and my 504. Those did not have any magnets but however, it's been a while and I can't really remember, but I think the 561A and the 564 had a magnet. I hope that this helps.

Jeff, ? I haven't worked on a Tek CRT but you should be able to look at the getter inside of the CRT and see if it has changed from bright shiny silver to dull greyish shite. If it has then the CRT has almost certainly cracked and let air leak into it and is beyond repair. Also I've never had to align a Tek CRT but on CRT based televisions, when you replaced the CRT you had to mechanically and electronicly align the CRT including applying magnets to various places on the neck of the CRT to adjust the beam.? It was not a simple job and it required a pattern generator. I have no idea of what Tek says about replacing CRTs in their manual but I wouldn't dive into the job without finding out what's involved first.
