Just be aware that there are at least two versions of this mains input/selector/switch assembly (well my two 7150's were different), and i think it depends on which input transformer is fitted!

You may need to work out which winding is which by measuring the primary resistances, and meter out the switch contacts, actuated by a tumbler cam, to work out the correct connections.

One of mine had damaged contacts, so I bypassed the voltage selector completely and wired for 240V permanently.

Peter
