There it is, in the July 1964 edition.....with a quarter million volts of firepower, it is powerful enough to get me and my friends banned from the high school science fair FOREVER!!!!
The Popular Electronics Big TC....Of course, even then building things according to the plans weren't big enough. Instead of a 3 foot tall Tesla Coil, we made it 5 feet tall. Instead of one sheet of glass and foil for the capacitor, we had a stack an inch thick. One of my friends found a transformer so big it took three high school kids and a shopping cart to get it into the classroom....the only name on it was "Budweiser".

Circa mid 1960's, the interior doors in schools and commercial buildings were often some kind of glued-up sandwich with some variant of Formica as the outermost skins. Now, Formica is an excellent electrical insulator - in fact, that's supposedly what the stuff was originally created to be.
The restroom doors at my High School had some huge stainless steel push-plates on them. Much larger than any functionality would require. Being the era of the "space race", perhaps that acreage of satiny brushed stainless was supposed to look "high-tech" to our adolescent eyes. Or maybe it helped the janitors, by not showing smudges left behind from poorly-aimed pushes. Now, stainless isn't a great conductor but it'll suffice as the conductive plate for a capacitor of a few picofarads.
At my High School there was a Boy's room directly across the hall from the Electronics Lab (yes, we had a full-fledged Electricity and Electronics curriculum in High School in those ancient days), and that restroom entrance was also just around the corner from the Physics Lab, where the Van de Graff generator was stored . . .
Although the potential was present, there wasn't enough capacitance to accumulate much net charge. And most of it dissipated before you could get the Van de Graff disconnected and stowed out of sight.

The RCA Review is very helpful, same with he General Radio Experimenter.
Now, if they could only get "Glass Audio" up there.

This is great documentation. Am sure it would be a great source of information.
Here 'Electronics for you' and 'Elektor' were the only popular magazines available. I don't know which magazines were published in 80s when Audio CDs came out. Would some gentleman guide me to any credible review of audio cd sound quality comparison against Cassettes/vinyls when they first came out ? It would be interesting to read reviews of that time period.
Thanks and regards.

Interesting that the SWTPC links also witness a contribution of J. Gordon Holt to PE in 1972. I think Sterophile was only 10 years old at the time.
All my PE's went into the tip about 10 years ago.
I still have a set from the first in 1954 to 1966. My first speaker was the Dave Weems $2.00 Celotex enclosure from the Nov. 1955 issue.
Dave Weems is still with us but at age 90, his hearing he does not allow him to any more speaker projects. I will be visiting him again later this month. I did a mini-biography on him in the October 2009 issue of Audio Xpress.
Thanks! What a treasure trove.
I guess there are "angels" out there who archive this stuff and make it available.

I've been downloading old Electronics Illustrated issues just for the pleasure of rereading Uncle Tom's Corner. He was a great influence on me.
Scott probably remembers the rash of "Thrifty 3-way" (another David Weems project) construction that happened on our dorm floor - I forget whether it was my freshman or sophomore year. The early 70's were the age of the acoustic suspension speaker.
Yes we used to put candles in front of the woofers and try and blow them out with the bass.
