Most of our items are sold through our ebay store.  We do have some larger or heavy items which are difficult to ship so they are sold pick-up only from the museum.  This page provides an overview of these items.  You can view them in person at the museum.

We also sale replacement eproms to repair 468 and 7854 oscilloscopes.   Please contact the museum for details.


Type 561A / 3A9 / 2B67 / Probe / Scope-mobile combination pack - $150.00

This combination package is for a 561A oscilloscope with the rectangular CRT which supports series 2 and 3 plugins.  The 561A mainframe can achieve a bandwidth of 10 MHz.  The 3A9 plugin is a differential plugin with a variable high-frequency cut-off from 100 Hz to 1 MHz and a variable low-frequency cut-off from DC to 10 kHz. The plugin provides a variable offset voltage when in DC mode and features a common mode rejection of 100,000:1.  This plugin is ideal for audio work with the variable high and low frequency settings.  The 2B67 timebase provides a single sweep from 1 uS to 5 Sec per division.  There is a single probe included and a model 200 scope cart.  The scope, plugins, probe, and cart are all in reasonable condition.  The handle on the 561A is deteriorated as most handles of this period are.  Switches and controls are reasonble but could benefit from cleaning.  Click on the image to view a large size.


Model 3 Scope-mobile - $150.00

This Tektronix Model 3 Scope-mobile is used but in good condition.  It will hold the larger 5000 and 7000 series scopes and most of the older 500 series scopes.  It does not come with any lock down straps which may be required for your specific instruments.  It has the shelf below the scope and the base for holding additional equipment and a drawer for probe and accessory storage.  There is also a four outlet power strip in the rear with a long cord.  We have multiple units for stock and some are missing the 5000/7000 series scope lockdown bar but since these are local pickup only at the museum you can check them out and decide which you want.  Click on the image to view a large size.

 

 


B&K 1570A 80 MHz Quad Trace Oscilloscope - $50.00

This B&K 1570A Quad Trace oscilloscope appears to be in fair condition.  It powers up and channels 1 and 2 operate.  Channel 1 appears to be about 10% low so could use some adjustments.  In Quad mode there are four traces but we are not sure they are working correctly.  With a signal input into either channels 3 or 4 the traces move offscreen.  Since this is not a Tektronix scope, we don't have the time to invest in understanding fully the operation or to calibrate it.  As such we are pricing it low for a four channel 80 MHz scope that you can invest some of your time to fully check out. There are no probes or IEC power cord included.

 


Goldstar OS-7020A 20 MHz Oscilloscope - $50.00

This Goldstar OS-7020A 20 MHz Oscilloscope is in reasonably good condition. There are a few dings in the metal case and portions of the front panel have a few minor flaws. It was opened and cleaned and operates fairly well. Some of the switches are just slightly intermittent but operating them results in a nice stable display. This oscilloscope would be great for audio work. It does not come with an IEC power cord or probes.


Kepco ATE 36-1.5M Power Supply 0-36 Volts 0-1.5 Amps - $25.00

This Kepco ATE 36-1.5M 0-36 Volts 0-1.5 Amp power supply appears to be in good condition.  It has not been tested under full load.  Since this is not a Tektronix product, we don't have the time to invest in verifying it.  As such we are pricing it low so that you can invest your time to fully check out. The power cord is not included.


 

Rohde & Schwarz Video Noise Meter 40 Hz to 10 MHz - $75.00

This Rohde & Schwarz Video Noise Meter 40 Hz - 10 MHz appears to be in good condition.  It powers up but we have not tested it.  The legends are in German.  It makes the noise measurement on a quiet line in the vertical interval.  It handles PAL format and may handle NTSC.  Since this is not a Tektronix product we don't have the time to invest in understanding fully the operation or to restore it.  As such we are pricing it low so that you can invest some of your time to fully check out.  There is no power cable included.
