The heavy lines on the schematic denote the primarysignal path.2. Unless otherwise noted, all voltages indicated on theschematics are measured under the following conditions:a. AC input at 120 volts, 50/60Hz.b. All voltages are +/-10% with respect to ground. A high impedance (10 megaohm) voltmeter must be used.4.On PC board drawings, Square pad indicates:a. Polarized Capacitors - Positiveb. Diodes - Cathodec. Others - Pin 15.WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.NOTESFM TunerUseable Sensitivity14dBF which is 1.4uV across 75 ohms50dB Quieting SensitivityMono: 19dBF which is 2.4uV across 75 ohmsStereo:
