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
