Commentary
This is an FM/AM receiver that can be used independently for pre-main and main.
The FM front-end section uses an FET and a frequency linear 3-row variable capacitor to improve sensitivity and interference rejection capability.
An IC and three ceramic filters are used for the IF stage, and an IC and silicon transistor are used for the MPX circuit.
The power amplifier uses a SEPP circuit to improve the damping characteristics.
The bus treble control can boost or cut in 2 dB steps.
It also features preset volume control, loudness control, balance control and microphone jacks.
