there a socket, or would wires be soldered directly to the pins?

Transformers are generally soldered in, and often last for the life of an
amplifier. Tubes are socketed because they are less reliable than a
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?

If you solder to the pins on the outside, the solder joints on the wires inside
may sprong loose. I've seen that happen (for real transformers, not this audio
stuff.)

I wonder what that thing costs.

718 US dollars for a pair apparently!

It doesn't look like the kind of thing designed to be soldered to, but
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.

I suppose the correct answer to the question (which should have sprung
out at me but did not), is "however the manufacturer intends".

Pick-and-place is easy for transformers, if you have the right gear.

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

Probably brass under whatever the plating is - and probably won't solder
unless you file down to the brass.

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.

That is a very significant point. Thank you for drawing it to my
attention.

it looks like there's a socket included with the transformer and that's
