Re: New member - Hi everyone!
Welcome to the asylum ... I mean party!
You can get full documentation (as PDFs) on most Tek scopes at either TekWiki (w1f0.com/tekwiki) or at the Boat Anchor Manual Archive (bama.edebris.com).
Here is the TekWiki page for the 465: http://w140.com/tekwiki/wiki/465
and the same at BAMA: https://bama.edebris.com/manuals/tek/465/
Careful, the TekWiki site, especially, is rocket fuel for the condition. I started out with two scopes that belonged to my father (a 475 and a 2213), that work more than well enough for my purposes (and could be made to work perfectly with the proper application of time, skill, and money). I now have half a dozen scopes, half of which are parts scopes for the 475, and two of which (a 475A and a 2215A) are completely new models that I lusted for after reading about them on TekWiki (and there is another that I am planning to buy, if I can just find a nice specimen at a reasonable price).
