When I was 8 years old I built my first crystal set, coil, variable capacitor and germanium diode plus headphones. It worked a treat I could receive Radio Luxembourg from my place in Cardiff Wales.
12 months later I built a 3 valve superhetrodyne radio MW and SW using a plywood chassis and 2 batteries 6.3V for the filaments and a 200V battery for the Anode high tension supply. You get immune to electric shocks after a while, as I had many off that 200V battery.
Building radios was the nerd hobby for kids in the 1950's and 60's. Especially with so much cheap war surplus equipment available for parts.
