1974 1st kit was Archerkit VOM, then SS Heathkit 10 meg single channel scope, and rotary switch frequency selected tube based audio signal generator, Audio VTVM.

And a hand full of various Heathkit/Zenith small household helpful type(flood alarm, freezer malfunction alarm, etc.) kits I assembled for friends in the mid eighties.
Sorry, don`t remember model #`s, though some equipment is in use on my bench, or house.
Heathkit was not always top notch, but usually a good value, and in my case, helpful in learning and understanding electronics for me during my early learning curve..
I was sad to see them go.
