Why no switchable power supply?

[DustyK47]

Here's something I've been trying to figure out for a while and even tried looking online for answers, but nothing. Perhaps it's an easy explanation...

I notice many JVC boomboxes (especially from the '80s) that have the "C" (for Canada) designation after the model number are not equipped with a switchable power supply. Why is that?

Maybe because local Canada consumer regulations for electronics do not permit it. Or maybe because there's no point since Canada uses only 120V.

 

[caution]

Likely a manufacturer decision. Plenty of products in Canada have a 110/220 switch

The transformer is smaller as it has only one winding. Multi voltage has multiple windings and can be sold to many different country's.
