1、VOLUME R-23, MOST-OFTEN-NEEDED 1963 RADIO SERVICING INFORMATION EMERSON Chassis 120547B, Models P-1908, P-1912 25L6GT RECORD P LAY E R RESISTORS IN OHMS AND 1/2 WATT, CAPACITORS IN MFDS, UNLESS OTHERWISE NOTED. * REFER TO CONDI TIONS FOR VOLTAGE & RESISTANCE READINGS (BELOW). EMERSON Chassis 120548B

2、, Models P-1907A, P-1916 EMERSON Chassis 120558B, Models P-1910, P-1917, P-1918 60FX5 1. Voltages indicated are positive d.c., resistances in ohms, unless otherwise indicated. 2. Measurements made with voltahmyst or equivalent. 3. All measurements taken from pin to B minus unless otherwise indicated

3、. 4. Voltage measurements taken with: a) Line voltage maintained at 115 volts a.c. b) Volume control set for maximum volume. 5. Resistance measurements taken with: a) Power line cord disconnected from outlet. b) Volume control set for maximum volume. 6. Nominal tolerance on component values makes possible a variation of 15% in voltage and resistance readings* 7. N.C. denotes no connection, K is kilohms, Meg. is megohms. 8. Resistances marked with * vary due to capacitor charge. Allow about 30 seconds for meter to settle. 36 收音机爱 好者资料库 RadioFans.CN
