All resistors and capacitors are in 2 and uF respectively unless otherwise specified.
Capacitors marked A are built in i-f transformers.
The symbol % indicates a component whose value is selected to yield normal operating condition.
Voltage values are measured from point indicated to ground circuit with a dc voltmeter (VTVM) and current values
are measured with a dc ammeter. Voltage and current are measured with no radio signal received. Varsations may
be noted due to normal production tolerances. The values in ( ) are measured with band selector set to FM.
