    I posted about this before but now I have more info. I came across this kit at a hamfest and now found it pictured in a 1970 Poptronics NRI add. See the PDF. Seems I have most of the parts, sans the tube sockets and tubes. The envelopes contain caps, resistors, selenium rectifiers, and even pre-cut hookup wire. There are 3 holes for 7-pin tube sockets. All I need are the instructions. Ring a bell with anyone? Would be cool to build this and experience a little '60's correspondence education.

    Believe it or not, National Radio Institute (NRI) registered the copyrights on each manual.

    Here are 1967 listings (Library of Congress) -- they were at "##T" by 1967 radio institute 2W experiments kit&f=false

    In 1968, McGraw-Hill acquired NRI ... and continued that practice.
    Terry -

    NRI, Cleveland Electronics, DeVry/Bell&Howell were Courses for Education/Credit.
    Heath-Kit was DIFFERENT in this approach.

    Kit would be tied to "Instructional Lesson" or Course, appears to be "2W" Instructional Lesson.
    The "W" should have been copyrighted by 1970.

    having taken an NRI course in early 60s, is suspect this was a partial kit that morphed eventualy into an AM radio.. Several experiments down the road. First power supply then audio amp, then the rest of the radio..
    just sayin'
