Seeing as how I am a ham radio operator, I have built many heathkits in my lifetime. Heathkit was a very big influence for a lot of us when we were kids just getting started. In fact, I still use the heathkit amplifier that I built back in 1975. it's sitting right here in front of me now, and I light it up every day!
After 37 years, it still is working like when i first built it. (oops, don't tell Obama, but I really did build it)
