I will be moving to Carthage in North Africa for the next 2 years where Mary Alice will teach at the American School and I will teach some Electronics, Photography and Journalism.  I need to unload some of my equipment before it (and I) age more.. And I can't ship most of this over there!  If you know of any electronics people in Tunisia, please let me know!   Click on the Model Number / Description at the beginning of the equipment descriptions to see a photo of each unit.

If you buy any of this equipment, we hope you'll also teach some kid how to use it!

Oscilloscope:   (Click on model number for picture)

Tektronix 7834 Storage Oscilloscope Mainframe  This is the industry standard modular scope, which can take numerous different plug-ins for vertical input signals and horizontal time bases. The storage capability is great for capturing nonrepetitive waveforms, and seeing slow waveforms clearly, but is unobtrusive when used as a fast 200 MHz + scope. See the following units starting with "7" for available plug-ins for this mainframe.  We will give preference to a complete deal with mainframe, two input plug-ins (for a 4-channel scope capability), and at least one horizontal time base (Asking $500 for package with either time base. Will include 4 probes with this, and some of the manuals that we have). Typically, a unit will have two 7A26 input plug-ins and a 7B85 or 7B92A time base, for a 4-channel scope system. Asking $300 for 7834 Mainframe

Tektronix Plug-Ins for 7000 series scopes, similar to 7834, above:
7A26    Dual Channel Vertical Input (200 Mhz)    Asking $100
7B85    Delaying Time Base                                  Asking $100
7B92A Dual Time Base                                        Asking $125

Tektronix Scope Cart   This is a classic! The early 50's chrome Model 500/53A Scope Mobile. If you are a collector of original Tektronix vacuum tube scopes like the 731 then this is the cart it once lived on! Marked "MIT Lincoln Laboratory: Govt. Property" . This is the famous WWII lab that developed RADAR. Asking $100 plus $25 packing unless you pick up here in Vermont. Works great with the Tektronix 7834 on it, as I've had it for several years. 

Tektronix 5000 series modular programmable test equipment
This is a series of modules and a modular power rack that can be programmed with GPIB commands from a computer or operated by front panel controls.  There are a variety of programmable multi-output power supplies, signal sources, signal scanners etc. This system can be used to make computer-controlled measurements for electronics production, device characterization, etc.
