For Sale Eico 667 Tube Tester
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. Les Locklear Gulfport, Ms. |

For Sale Eico 667 Tube Tester
I have a 666. What's to calibrate?
Two pots inside, with a VOM across the AC primary transformer tap and set to 130VAC with the line-adjust pot. One pot is then set to full meter deflection (adjacent to the filament selector switch), the other to 1/2 meter deflection (adjacent to the line-adjust pot) with various buttons pushed. Takes 10 minutes apart from removal and installation into the case. Did mine last night. Does not have sockets for pre-octal tubes, but does run well up into the compactrons and nuvistors. And it lists a lot of the pre-octals on the chart, so there must be adaptors available. Calls itself a "dynamic conductance" tester. Weight is about 12 pounds, or so. Not overly large. Good, easy-to-read meter and very easy-to-roll tube chart. Eico has a reputation for errors on its early tube charts, BTW. Now to trace a niggly little fault, and intermittent to boot... the worst kind. I expect it is a bad connection combined with a wire-or-two out of place so that the problem only shows on occasion. If I get it fixed, this one will go at Kutztown. I snagged it as the price was right, but it is not a keeper... and of the three I have, it is the least appealing. The other two do the older tubes as well. Peter Wieck Wyncote, PA |
