This tester was rebuilt and calibrated in January, 2005 by the late
Chris Haedt who was considered by many to be the "Professor of Tube
Testers."

It is a late model 667 without the built in roll chart, has a full
manual copy and repair report and calibration sheet from Chris.

Extremely clean, no longer needed here as I have cleaned out the
boatanchors. It will not test the older 4 pin tubes.

This is a solid state unit and very reliable. It is a dynamic
conductance tester.

$100 plus shipping/insurance.
