According to that diagram it is indeed switchable, but how - can't tell you, you need to look for the place where the primary leads terminate, likely there is a barrier block or some kind of jumper arrangement that should be changed. Follow the leads.

If it is that easy, then why didn't Hall make the switch, and earn some fast money? Don't get me wrong, I'm with you, Mr. K. After looking at the diagram on the top of the transformer, it should be exactly that easy. The only thing the transformer doesn't tell you is what color lead you would use to convert it to 220V.
MEDiASAPiENS, have you taken the bottom plate off, to see if there's any markings on the underside of the transformer? Mr. Khomenko's right, that's your next step.
Good luck with it.

First one - there are FIVE possible voltages, so it would have to be one complicated switch.
And second one - a permanent connection, with spade lugs under screw terminals, will always be much more reliable, than any switch.
I didn't mean a physical toggle switch. What I meant was that I wondered why Hall didn't make the change , meaning why didn't he unsolder the 120V lead, and connect the 220V lead. Switch places, in other words.

A detachable cord set or a permanently attached power cord?
...most likely lies with their policies. I can't speak for that aspect.
I wasn't expecting you to speak to it, of course. I know there's no way you could. I was simply pondering why a company might build a receiver using a more expensive multi-tapped power transformer, and then not do a simple conversion on something which was hand delivered to them.
I suppose we'll never know.

total BS really. No excuse. An easy change.

It does seem somewhere between odd and silly they didn't do the work considering the part MH chose to use.
