    • Stereo/Mono selector (Stereo via headphones)
    • Audio output:
      • 300mW at 10%THD via the internal 8 Ohm speaker
      • 5mW+5mW over 32 Ohm headphones

     

    Brief technical details:

    The FM band uses a dedicated TA7358AP (IC1) front end that connects to a TA2057N (IC2) shared with MW, LW, and SW bands. The SW band RF front end uses discrete FET and bipolar transistors to implement dual conversion of the signal that is in the end passed to the shared TA2057N (IC2). A pair of AN7117 (IC4 and IC5) handles the audio amplification. Two regulator ICs are used in the power supply, one LA5003 (IC3) 3VDC for the main PCB, and one S-812C30 (IC202) 3VDC for the MCU PCB.

Hello,

I found interesting problem in this radio.

On page 13 service manual (processor board) on the left upper corner is note1 about optional diode D201 (RLS4148) for ITALIAN option this board.

My question is: What is difference between Italian and CE versions this radios ?

Regards

Damian
