I have fond memories of constructing about a half dozen Heathkits in 1969. I still have them and did some restoration work on them two years ago. I'm looking forward to using them to restore several antique radios I recently purchased.
I was saddened years ago when the Heathkit store in my home town closed. I had planned on constructing one of their more elaborate oscilloscopes but never got the chance.
Now all the amateur-grade test equipment is imported, available at Fry's.
Fry's is the righteous replacement for the Radio Shack store. They have everything RS ever had, and more.
