Diagram of Tuner Chassis RC-1206A is on the next page, over; and the diagram of the amplifier is on the page following. Use this related material together. The l-VE-2 Series, the l-VF-l Series, and the l

3、-VF-2 Series instru ments use a lour tube dual-channel audio amplifier (RS-193A) con sisting of a preamplifier stage and an output stage in each channel. The phono input and the tuner input are fed to the function switch which selects STEREO phono, MONO phono, or RADIO tuner oper ation. Dual control

4、s are provided to regulate the BASS, TREBLE, and LOUDNESS In each channel simultaneously, and a BALANCE control is provided to permit adjustment of the relative strength of each channel. The RS-193A chassis contains output jacks for AC power to the record changer and to the tuner. A multiplex power

5、output jack provides filament and B+ power for a multiplex adapter. The 1-VE-l Series instruments use the RS-193B audio amplifier which is similar to the RS-193A except that it does not contain a function switch, a tuner input, a tuner AC power output, or a multi plex power output. The l-VE-0 Series

6、 instruments use the RS-193D audio amplifier. The RS-193D chassis is similar to the RS-193A except that it does not contain a function switch, a tuner input, a tuner AC power out put, a multiplex power output, or a dial light. MULTIPLEX ADAPTER Models of the 1-VF-l Series and the l-VF-2 Series have

7、provi sion for the connection of a multiplex adapter (RCA Model RK- 295). Three jacks provide for the input, output, and power con nections of the adapter. The signal input jack (Jl) and the signal output jack (J2) are mounted on a bracket fastened to the cabinet underneath of the AM/FM tuner (RC-12

8、06A). (These jacks are shown as a part of the tuner circuitry.) The MPX POWER jack is mounted on the amplifier chassis (RS-193A), and provides fila ment and B+ power for the adapter. To receive FM multiplex broadcasts: 1. Connect the cables from the multiplex adapter (RK-295) to the MPX INPUT jack (

9、Jl) and the MPX OUTPUT jack (12) on the tuner chassis, and the MPX POWER jack (J205) on the amplifier chassis. 2. Turn the FUNCTION selector switch to FM MPX. 3. Turn the STEREO-MONO-RADIO switch to RADIO. 收音机爱 好者资料库 RadioFans.CN 102 收音机爱 好者资料库 RadioFans.CN 103 收音机爱 好者资料库 RadioFans.CN VOLUME R-23, M
