Way back my very first introduction to electronics was the construction of a crystal set using the Repanco coil,
a 500pF tuning capacitor, a germanium point contact diode and a set of the then popular magnet and tin
diaphragm headphones. All the parts came from Roy Pitt's surplus store in Picton Street, Bristol.
It was built on an ebonite panel and housed in a mahogany case lovingly crafted at school woodwork classes.
The aerial was a 50ft length of army telephone wire strung from my bedroom window down to the rustic fence
and the earth was a copper rod sunk into the lavender bed.
I was able to lie in bed and listen to programmes on the Medium Wave Home Service, 206m,
or the Light Programme on Long Wave, then 1500m.
