National Panasonic RF-1103 Variable Capacitor

The RF-1103 has a multi-stage variable capacitor for tuning into radio stations. This type of capacitor usually contains separate stages for the oscillator circuit, however, when I was building a crystal radio, I was able to use a recycled one like this by connecting all the stages in parallel to make one larger capacitor of 300 pF value.
