I first encountered Heathkit
when working at GCHQ in Cheltenham. For some reason which escapes
me now, I decided to construct a metal detector and found it
worked but was not very sensitive. In 1970 the Internet wasn't
around but I managed to find out that Heathkit sold a metal detector
so looked up their nearest address in the local phone book, found
that they had an office in nearby Gloucester so drove over there
to see if I could buy a metal detector from them. I didn't buy
one but picked up a leaflet describing it and this included a
thumbnail drawing of the circuit diagram. Maybe the detector
was too expensive or were not available off the shelf but I returned
home without a metal detector but determined to build one using
their circuit diagram as a guide.
After a week or so my pseudo-Heathkit
detector was built and a friend and I were searching for treasure....
but that's another story.
Below I've listed most of the
Heathkit products I've collected over the years. Some awaiting
