Heathkit IT-3117 Tube Tester - Calibrated! - HAM
Here's a nice, clean Heathkit model IT-3117 tube tester. It's the last of the Heath tube testers and has virtually all the sockets you could possibly want.
Separate sockets are provided for the older 4-pin, 5-pin and 6-pin tubes, as well as the expected 7-pin miniature, 8-pin octal, and loctals. It also has sockets for both 5 and 7-pin nuvistors plus 9-pin noval (miniature) and novar, and 12-pin compactrons. 10-pin miniatures (Did you ever see one of these? There were only two.) are accommodated with an extra connector in the center of the 9-pin socket. In short, there isn't much you can't test with this instrument. The test circuit of the IT-3117 is identical to Heath's earlier models TC-1, TC-2, TC-3, IT-21 and IT-17; and the test data is interchangeable. The Heath circuit was borrowed from the Triplett 3413. Eico and Allied Radio also licensed this circuit for the Eico 625 and 628 testers, and the Knight KG-600 series of testers. All the data for these instruments is interchangeable, giving a vast database of testing information. If you can't find the test you want on your Heath chart try a different Heath chart or an Eico or Knight chart! You'll surely find it in one of these places.
To ensure accuracy of the competed kit, Heath didn't provide any calibration adjustments for the IT-3117, but relied instead of the inherent accuracy achieved by using close tolerance components in the measuring circuits. Calibration consists of ensuring that all of the components in the measuring circuits, including the meter, are still within tolerance. This has been done, and this IT-3117 is working as it should on all ranges. It is shown in the second photo testing a new 6L6GC tube. The tube, of course, is not included in the sale.
Included, however, is a clean re-print of the operating and maintenance sections of the manual, including the schematic. Also included is a re-print of the obsolete and seldom used tube data originally released for the TC-2, but never offered again. It's a gold mine of testing data for those old 2 and 3-digit tubes found in vintage radios. And yes, you can use it with this tester.
This instrument is in very nice condition with only a few scratches as can be seen in the photos. The chassis is clean and bright and the wiring very neat and professional.
If you want a tube tester that's very popular, is in good condition, has lots of data available, and will test all your vintage tubes plus the newer ones, you'll be pleased with this one!

My name is John. I'm not a professional seller, just a retired electronics engineer selling off my collection of electronic equipment acquired over the last half century. Some of the kit items I built myself back in the mid '50s. Newer items I acquired as I needed them for my work and hobbies. A few older items I bought on just for the joy of fixing them up and seeing the vacuum tubes glow again. Most all the items I'm selling are in good working condition. The few that aren't will be plainly stated as such. All items will be accurately described to the best of my ability. These are not collector items, just good working tools that have lots of useful life left in them. They are sold as-is, but will leave my possession carefully packed and in the condition stated. I look forward to your business. Good luck with your offerding!
