socket, and often must be replaced during the life of an amplifier.
Sockets themselves become a potential failure point, and they cost
money. So why add expense and diminish reliability?

the terminals don't look real friendly either - bullet quick-connects?
Are those screws in the corners to mount it with?

Transformers are often chassis-mounted, because they're heavy.

So, to connect the transformer to a printed wiring board, it's
VERY common for a PWB to have a socket for the transformer
connection. The flexible leadwires from the transformer
are soldered to the solid (inflexible) windings, though.
Transformers (and other inductors) get a bad reputation partly
because it's difficult to put them through 'standard' pick/place/solder
operations.

If it's a current production part, you could ask the manufacturer.

Probably brass under whatever the plating is - and probably won't solder

Since the transformer has tapped holes at its corners which are no
doubt intended to secure it to a chassis, and since sockets are very
rarely mounted with their tops flush with the chassis' top surface
and secured with flathead screws, it's likely that the transformer is
designed to be chassis-mounted with its terminals protruding downward
through a circular cutout in the chassis.
That's further attested to by the nicely bright solder blobs on the
ends of the terminals which, by no stretch of imagination, could be
designed to be socketed.
Blow up the photo and it becomes apparent that there's no index key
for the socket and that the terminals, which seem to be turrets, are
yellow.
Gold over nickel over brass?
Not unlikely for a high-ticket item.
