According to the Trader Sheet (817), the mains input pins do indeed go to the double pole switch and from there to the voltage selector panel and mains transformer primary. There are no other components (such as fuses or filter capacitors) shown.

So I feel that the polarity of the mains input is unimportant.

And as others have said, the A and E sockets are for Aerial and Earth. They are sockets on the chassis, not pins, and are at the other side of the chassis to the mains input.
