Would you believe me if I told you all that one of the first electronic
kits I built as a kid was an intercom, a simple audio amplifier. It
used three germanium *transistors*. Neat kit from General Electric.
Early 1960's. It is in a clear plastic housing about 3 x 8 x 10 inches,
with the circuit diagram painted on a masonite board that holds
spring-clips into which all the components are fastened. No soldering.
Each resistor, capacitor and transistor is positioned right above its
symbol on the diagram. I still have this, and I think it still works.
Those transistors are really wild looking, large metal cans.
