I knew Pete had a lot of experience with transistors, but I didn't realize just how far back this experience reaches. Pete writes, "The March 2015 issue of QST had an article about a 1953 transistor transmitter project which was really advanced technology since the transistor was only invented about 5 years before that time... About 1953 at the age of 11, I built my first solid state audio amplifier using the venerable CK722 from Raytheon. The transistor did look a bit strange in that cool blue cube shape with a red dot on the side to identify the collector. What a joy and surprise to me that it worked the first time power was applied... It was the CK722 that in large measure started me on a life’s work and engagement in a wonderful hobby. That CK722 path also led me to designing and building a QRP solid state version of the Collins KWM2 which I call the KWM-4." I asked Pete why an 11 year-old kid in 1953 felt compelled to build a solid state audio amp. The answer is very cool: Pete's father had introduced him to crystal radios at age 8. Pete wanted an amplifier for his crystal set, but his dad was worried about him building high voltage tube gear. So that's how Pete got his VERY early start with transistors.
We are really lucky to have Pete Juliano sharing his vast tribal knowledge with us.
In response to popular demand, "SolderSmoke -- Global Adventures in Wireless Electronics" is now available as an e-book for Amazon's Kindle.

For the print version:
For shipping from a printer in the U.S. (probably better for N. American buyers) Click here: SolderSmoke USA Version
For shipping from a printer in the UK, Spain, or the USA (probably better for UK and other European buyers)
Click here: SolderSmoke EU Version
The two versions are identical, except for a minor difference in the paper used. That's why the prices are a bit different.
