December 16, 1947 ( sixty years ago ) the transistor
was developed by John
Bardeen , Walter Brattain, and William Shockley from Bell Labs.
And 10 to 15 years before that, ARRL, in its magazine QST, published
schematics and all the other necessary info to build a solid state
audio amplifier. I seem to remember 1932 or there abouts.
The rest, as they say, is history !!
