Hickok 6000A Mutual Conductance Tube Tester 
 
Please see the calibration report in the pics for further details pertaining to the specs and important information (Pictures 6, 7, and 8)
 
Exceptionally clean and beautiful condition!

The tube chart is also dated 1966.

The tube sockets on the tube island look unused, and the noval, 7-pin min, and compactron sockets look as good as new.

New meter is calibrated to spec and is smooth with no banging.

The shunt was also cleaned to ensure accurate mutual conductance test results.

Includes a manual with a schematic, foreign and obsolete tube data book. I can include a DVD upon request with more tube data and manuals, or can send the files via email in PDF files. 

Please see the calibration report in the pics for further details pertaining to the specs and other work done.

The test adapter, multimeters, and calibration tubes that may be seen in the pictures are not included.

A DVD with manual and tube data will be included on request, or I can email the contents of the DVD. The DVD is shown in the pictures but not included unless requested since many no longer have a DVD on their PC.
 
Please see the calibration information in the pictures.
