The circuitry used in this portable radio incorporates 10 transistors, 3 diodes and 1 thermistor. A bar antenna feeds the MW broadcast signal to the mixer. A rod antenna feeds the SW broadcast signal to the mixer. Local oscillator voltage is fed back to the mixer. After going through 2 IF amplifiers and 1 diode detector, the signal passes through a 5 transistor audio amplifier. An AM amplified AGC voltage is fed back to 1st IF amplifier.
