solder sucker and solder wick , plenty of luck , work fast (shortest time possible per pin/cycle)

use fat tip , only way for fast heat transfer

be gentle with tweezers , when wiggling pin in hole

only when you free up all pins with wiggling - try to pull xformer out

Use flux on the joints when you desolder,even when using a solder sucker.Its messy but works better than a dry joint.

Where in Sydney are you? I've got a vacuum desoldering gun. I can get it off the board for you.
