Unlabelled and disconnected mains primary wires

You can have multitaps on dual primary ones for variants on the theme of

110/240V, so not an exclusive term

You're not looking for answers, are you?

"Nutcase Kook is So Full of Shit "

** Wot a load of utter bollocks !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Most audio amps made in the ** UK ** between the mid 1960s and late 1990s had multi-voltage, single winding AC transformers.

Check any old schem from Marshall, Vox or Sugden etc, et alia.

You're right- they must have just cheapened their transformers. Condor stuff used to have the 5 terminal primary windings. If you can find a manual for an older generation "international linear power supply" how those windings are setup is diagrammed.

They're not a single winding though, and not nearly as wasteful as 50Hz mains frequency when it comes to excessive use of materials and size.
