Classic Mutual Conductance Heathkit TT-1 Tube Tester. Picked this up from a fellow ham radio operator that was into tubes and tube testing many years ago. I was thinking I would fully restore it, but just never got to it, and moved on to other interests.
The EICO Model 666 Dynamic Conductance Tube & Trans. able to test both tubes and transistors. Among its advantages are rapid and simple operation, close simulation of actual tube operating conditions, and unexcelled thoroughness and accuracy of test.
This is a beautiful working example of one of the finest tube-testers ever built. It is one of the last of the great Hickoks and has been very lightly used. The roller tube-chart functions properly and has the test-data for many modern tubes not seen on other testers, such as 5687, 5755, 5670.
Brand new pump that I purchased for a project and never got around to. I took it out of the box, verified that it worked, and put it back. This pump is wired for 120v.
This machine is in fantastic shape and has been greatly taken care of. If you have any questions please feel free to contact me anytime. DIES ARE INCLUDED!
