Oppie - which "electronic experimenters handbook?"

Hello,

I don't have the magazine with me now but I believe that it was published by "Popular Electronics" magazine. There were quarterly handbooks that had the best of the articles published in the regular magazine and organized by type. Magazine got a chance to resell old material with the occasional new article.

I remember one construction article for a telephone answering machine (Circa1959 in electronics illustrated) that used NE-2 lamps for all the logic elements. the lamps had to be burnt in and then selected for voltage. The audio portion was kluged from an old phonograph. Being only 8 at the time, I couldn't fully appreciate the article. Went looking for it recently and couldn't find it. Must have lost some stuff in a move.
