I change one in my AG-35 just cut the legs of the fried one as close to the casing possible then just solder the new one over the legs
already solder to the board. To avoid over-heating the coil relay just put a piece of insulating material over the coil i put a small piece
of teflon. There is only one leg too close to the coil relay. You should have a steady hand and a magnifier with a lamp it help to avoid
messing with your pen iron throwing melted solder all around the place.
It works for me just hope it will work for you.
