Default Trying to match small AC transformer - 240V primary 12.8V secondary

Hi all,

Having found an open primary in the small transformer providing standby
power to a Yamaha home theatre receiver, I want to source a replacement
of course.

The transformer is marked on the side:

XW608 AO
TAM M 0118

and has no voltage or power specs on it. On the schematic there is a
voltage shown across the secondary of 12.8V AC; the primary is 240VAC
since this is an Australian unit.

The transformer is physically small (about 30x30x30 mm, or roughly an
inch and a bit on each side) so I am guessing it has a rating in the
milliamp range for the standby switch, IR receiver and a relay to switch
on the main PSU.

Can anyone offer me guidance on sourcing a replacement? Searching for
the markings via Google hasn't turned up anything useful.

Thanks for any help,

Matthew.
