Yes I do. I remember buying the "P-Box" kits and building them. The one tube AM radio, blinky light (several neon lamps that could light in sequence or random), OTL amplifier, and the wwv converter are some I remember building. I remember the magazine put out by rat shack called "Elementary Electronics". (The magazine had so many cool projects you could build.) Buying a 3 pack of ferrite loop stick coils and some germanium diodes and making crystal radios. And the free battery each month with the battery card. And as a teen I bought the Modulare 8 am/fm eight track tape player. Crap now but boy it was a cool stereo back then.
Yes, truly a blast from the past.
