[NJARC] NRI 70

[Joe Connor]

Steve:

     1. Here's the link to the Operating Instructions/schematic for the NRI 70

http://bama.edebris.com/manuals/nri/70


     2. Here's a site with photos of a lot of Precision tube testers. Perhaps this will help you correlate yours to its Precision equivalent:

    3. That website I sent you several days ago has a link that permits you to purchase all the paperwork for the NRI 70.

    4. I've used a Precision Model 612 for years and have found it to be an excellent, reliable tester.

   I hope this helps.

>Got my tube tester last night..that NRI 70...$17.50 at the auction...wonder who/why the other bidder wanted it??...( found no treasure trove, alas. )
>
>Anyway...it seems like the NRI unit was made by Precision...who made identical models using their own nomenclature...all in their 600 series models.
>
>Found the Precison 600's schematics & manual on line...might take me a "while" comparing all those schematics to the wires in my unit.
>
>Anybody know which Precison model 6?? is the NRI 70?
>
>Also, there's a clipped wire protruding in-between 4, 5, and 6 pin sockets...might this be the grid cap lead?
>
>Now...on to the bench with it....
