    Hello,

    I have a Optimus STA-300 Tuner Amplifier passed on to me. It was purchased from Radio Shack in the US.

    The FM / AM band is set to select frequency band in US and not to that in India. Since it uses a PLL Frequency Synthesizer, it should be possible to change the Frequency selection settings.

    Besides, I'd like to alter the power supply for a 220 V input.

    Can one of you please help me with a schematic?

    Thanks,
    Ramesh
