Maybe, maybe not. It depends on location. Thailand, for one, uses a two
prong plug that looks like a standard U.S. item, but is used with 220 volts.
Hong Kong uses many different plug types with 220v, one of which is the same
2-prong style. I think, if memory serves, that Myannmar, Laos and perhaps
Malaysia are the same -- Regards --

If he had "converted" it, it would be easy to work out. If it didn't have a
220Vtransformer, he'd have to install one. The solder joints would be a
giveaway.

Lots of trolls patrol these waters....

Not likely. For many years most voltage conversion is done by
changing taps on the line transformer. Either by a switch or
on older gear, solder connections. No tranformer change.

Real cheap electronics might have a 220 v tranformer, but
a tape deck would probably have a 110/220 v transformer.
