content: Hey everyone! I was able to score 3 parts TEK 2465A scopes today for next to nothing. 2 are missing the CRT and the one that is there is very weak. That being said....I know how much people cherish these scopes (As do I...own 3 of them) I would offer for free one of U800 I have if anyone is truely missing their scope being operational. Just PM me and I can pack it properly and send it to you in the proper packaging. I only have one so first come first serv!Jeff

content: Question to any TEK 465 users. How would you compare the trace sharpness on those compared to the 2465a? I remember reading an article about a compromise on these newer scopes which produced a slightly less defined trace. I have the possibility to get one with original cart from the same place I got the donor scopes but it doesn't fire up. It is in almost mint shape so I was inspired by the 465 teardown on here and would love to restore it. I am totally obsessed with Tektronix these days. The company was and is responsible for so many innovative products!

content: I have a 465 and a 2445A. I'm not really sure if the 2445A has the same CRT as a 2465. When carefully adjusted (brightness, focus, astig), both scopes will produce nice sharp traces. (See photos.) The 2445A might be just a bit better to my eye, but not by much. I can't remember using one of the scopes that have a reputation for ultra-sharp traces (5xx series?) so I don't really have a benchmark for how these units I have compare in that regard.

content: Thank you for the pics! I do believe it is the same CRT as the 2465. The 2445 does actually look a little sharper. I think I may still grab the 465 though. Something I am really digging about that scope. And really wanting that cart too! Oh yes. The 500 series. I myself have never tried one either. Thanks again for the reference pics...I really appreciate it!Jeff

content: I had a 465 for a good few years in the back of my car when I was a service engineer.Built like a tank and a joy to use (and yes it had a nice sharp trace) Got rid of it in a clear out and have regretted it ever since,. Would love another one but have 2 other scopes that do all I need so not really on the cards, Still a nice scope though.

content: I would agree, the 2465A that I have is slightly sharper than the 465B. But, the 465B screen is slightly larger. Neither of them can match the sharpness of the 485 and the 2467 though - although the screen sizes of these latter two are smaller than the 2465.

content: I have noticed that when you use the 485. There almost seems to be a 3 dimensional quality to the display as well. I have checked them on Ebay and there is not many of them. The ones that are go for a pretty penny. By the way Alan I love all of your videos and have sent your youtube links to many people that I talk to who are just getting into electronics and want to understand their scopes in more detail. Brilliant! They are also one of the big reasons I am constantly lusting over Tek scopes!
