1、MANUAL OF MOST-OFTEN-NEEDED RADIO DIAGRAMS The Crosley Radio Corporation, Cincinnati, Ohio /VVVVVVVVVVVVVVVVVVVVVVVVVVVVVV* Model 169 Specifications Model 169 is a four tube dual band super heterodyne designed for operation from A.C. electric circuits. The intermediate frequency is 456 Kc. Tubes and

2、 Voltage Limits The following are the tubes and voltages measured with the receiver in operating con dition but with no signal to the antenna cir cuit, with a line voltage of 117.5 volts (235 volts for 220 volt receivers). All voltages, except filament, are measured with a 500 volt D.C. voltmeter (1

3、000 ohms per volt) from tube contact to chassis. Filament volt ages are measured with a low range A.C. voltmeter.
