1、VOLUME R-23, MOST-OFTEN-NEEDED 1963 RADIO SERVICING INFORMATION GENERAL ELECTRIC MODELS RC1611A, RC1616A, RC1616B (Circuit diagram on the next page, adjacent at right) TUNER - The RC1616A series used the TU-20G tuner and the RC1616B series used the TU-20C tuner. The difference between the tuner mode

2、ls is the type of selector switch used. The TU-20G utilized a thres position selector switch (AM, FM, FM-AFC) and the TU-20C tuner used a four position selector switch (AM, FM, FM Stereo, and FM-AFC). The FM-AFC position on the TU-20C tuner is actuated by a push-pull switch mounted on the selector c

3、ontrol shaft. This places the FM stereo switching on the TU-20C tuner selector and changes the RC1616B function control switching to PHONO-OFF-TUNER- TAPE. This required a small wiring change to the function switching circuit as shown in the RC1616B schematic. A modification to the scratch filter ci

4、rcuit has been incorporated in the RC1616B series beginning with serial number K294001. It results in the elimination of four cables to the scratch filter switch and better component assembly in the powe amplifier.
