: I need info on this oscilloscope. All I know is that it is a 35MHz dual trace. I tried sourcing a manual from AG Tannenbaum's site, no luck. What kind of probes should I use with this unit and where else might I find a manual?
The 442 was a short run for Tek compared to most of their scopes and you'll not find many of them around. It was manufactured around the late 1970's and early 1980's, and its design is kind of between the 400-series and the 2200-series. Even working for Tektronix, I can tell you that I never laid hands on but one or two of them, where several hundred 465's, 475's, 7704's, 2213s, etc. ran by me. Tektronix may still have a manual available and certainly will have one available on microfiche if nothing else (usually cheaper than a paper manual anyway). They're at http://www.tek.com . Used micirofiche readers in this day and age of CD ROM are available for chump change.
Now that we've determined the model number, you'll find that the Euro site that Don mentioned won't be of much use to you since it's primarily devoted to the older 500-series of the 1950s and 1960s.
But here's some sources for manuals that deal primarily in test and measurement equipment:
http://www.agtannenbaum.com
http://www.manualsplus.com
http://www.w7fg.com/manuals.txt
http://www.ac6v.com/pageaae.html
But your best bet will be off-line with:

As he mentioned, the model number will be most helpful, including those of any plugins, if any. Most of the older Tek 35 MHz scopes were the 545 series.
Probes for that frequency range can be found in most general catalogs such as that of MCM Electronics. If you pay more than $35 for a new probe, you're paying too much, unless it's a Tektronix (brand) probe. If the scope/plugin has a UHF connector, you'll also have to buy a UHF-to-BNC adaptor to use any probe made after 1970.
