Well, since Japan analog TV was also the North American NTSC format, this would have worked pretty well over here. Granted, PAL and SECAM, were superior colour analog formats, but North America was their biggest market. We still have Digital off-air ATSC to analog NTSC converters over here, and I can still show-off a black & white 5 inch portable TV that I have from 1979. So, good chance that Sony TV / radio / cassette combo was not made for a PAL format TV market, but could still play as a novelty here. Interesting insight, thought. Merci & soixante-treize.
