Master description

Vintage Tektronix 7704A modular oscilloscope system with Tektronix mobile equipment cart, four installed plug-in modules, additional accessories and extra Tektronix equipment.

This came from an estate workshop belonging to a radio/electronics hobbyist. The workspace contained numerous radio components, speaker drivers, test equipment and electronics parts. The oscilloscope also retains an older Hughes Aircraft Co. property label; I do not have documentation connecting the previous owner to Hughes, so the label is simply being shown as found.

Main system includes

Tektronix 7704A Oscilloscope System

D7704 display section

A7704 acquisition section

Two 7A12 Dual Trace Amplifier plug-ins

7B85 Delaying Time Base

7B80 Time Base

Tek lab cart model 3 Scope-Mobile style equipment cart

Additional loose 7B80 Time Base shown in photos

Probe/leads, paperwork/data sheets and miscellaneous Tektronix accessories shown in photos

Testing performed

The unit has been powered on and basic operation has been verified.

The CRT illuminates and produces a clear visible horizontal trace. The trace was centered and adjusted using the front controls. CRT readout is functioning, graticule illumination works, Beam Finder responds, and the installed plug-ins power up with indicator activity.

This has NOT been fully bench-tested or calibrated. I have not verified every input, channel, time-base function, bandwidth specification or calibration accuracy. The internal calibrator/input signal path was not fully tested.

It is therefore being sold as partially tested vintage laboratory equipment, not as recently calibrated professional test equipment.

Cosmetically it shows normal age, workshop use, dust, marks and wear consistent with vintage laboratory equipment. Please review all photos closely.

This is a substantial, heavy setup and I am selling it complete as shown rather than shipping the entire system.

Local pickup in the Anaheim Hills / Orange County area.

Excellent piece for a vintage electronics collector, radio technician, restoration shop, Tektronix collector, electronics lab or retro test-equipment display.
