I've fixed a few of these and I don't have parts lists because there are a lot of different versions. I can't remember which configuration they originally used in 2235 or what the updates were/are, but here's a good copy of the manual.

TekScopes@groups.io may have more specific and detailed information, but if not it isn't that hard to figure out as you go along. That's what I do because I can't remember all the details from one unit to the next!
Some seem to have it all burned into their brains, not me. If you have dimensions and so forth but have questions as to which caps need replacing or what versions to use, post back and you'll get opinions. My first opinion is that if the scope is working properly now, tread lightly and just do a bit at a time.
