I had a Heathkit 25" color TV for many years. It was a hybrid set (i.e. half transistor and half vacuum tube circuitry.) A neat feature was it had a built in dot generator, so I could do alignments without the need for bench instruments.
I did, my first scope was a Heathkit I bought about 1976 or 77. I was 13 & we didn't have a Heathkit store in OKC. There was one back then on Ross Lane in Dallas. My family went to go to Padre' Island for vacation back then a couple times, so I got my wish.
Sometime soon after, I got one of the Heathkit trainer things too, had breadboard with 5 volt supply & variable power supplys & basic sine, squarewave generator built in.
My dad still has an amp he made- I think in the 60s but perhaps the 70s. It had a green tuning bar that took up most of the front, 4 knobs and a row of buttons across the bottom. Cool for the time.
I built a stereo amplifier in my early teens, worked well for a kid just learning to solder. Had enough power to get my parents to yell "turn it down!!!". Dad said the bass gave him a foot massage as he watched TV upstairs.
Thanks for reminding me of these, maybe I should be less of a chicken about the car's electronics.
I didn't have any mind-expanding stuff as a kid.
As soon as I could work, I had to work. My meager checks or cash from my paper route or lawn cutting helped pay household bills. It was that way until I graduated from high school and put myself through college.
I always wanted to build a Heathkit radio...never did.
