That was purchased new in Hong Kong, which was the only 220V market these were sold in at the time. My personal 2000f also is ex HK. Smooth knob versions are Japanese market only, Jagged knobs were for export.
Hi! I know this was done 3 yrs ago so I am just hoping that you will pick this up. I have just received out of Japan the Sony ta 2000f set at 100v. I live in Australia which is 240v, looking at the selector switch I could set it to 220v which is okay but I can't move it. I've unscrewed the 2 screws to see, just a mass of wires. Can you identify what I need to do to set it to my countries setting ? I tried to pull it up, thinking then I can swivel it, but I dare not force it as it is stuck. Thanks Alain
