Too bad I didn't have the insight to save my old Radio Shack and Heathkit catalogs from the 70's... Oh well.
Thanks for the trip down memory lane, Fran! I remember those pages. I used to pour through those catalogs, page by page, when they arrived in the mail. I built several of those pieces of test equipment, and still have a few (Grid Dip Meter, FM Deviation Meter, a few transistor checkers, etc.).
I do still have a set of Tektronix catalogs - from '65 on up.
