There's a www.heathkit.com that carries some of the same educational kits
that the old Heathkit used to, and it's in Michigan.
===========================
And even in the same place.
From the training kit on offer I recognise a similar design as the ET-3300
Laboratory Breadboard , I bought in kit form in the mid 1970s ,which I still
use on a regular basis.
Heathkit is definitely not dead,be it they now supply somewhat different
products,to suit today's world...................good to see that !
