EICO MODEL 666 VACUUM TUBE AND TRANSISTOR TESTER - WORKING For Sale

Up for sale is a working vintage EICO 666 Dynamic Capacitance Tube & Transistor Tester. This is a working vacuum tube tester which I used in my vintage audio restoration business for around 10 years. I calibrated it when I first bought it and never had any problems with it.Included is the most recent release of the tube data and test settings, newer than the built-in scroll and more accurate. Unlike the newer EICO Model 667, this tester has sockets for some of the oldest vintage radio tubes.I never used the transistor tester so cannot comment on whether that feature works or not.
