Hi John
With everything in the service position, all you have to do is gently push the transformer from the inside towards the outside. You will find that the transformers plug slots over the 12 pins on the left side of the board. Apply some gentle pressure in this area and the transformer will separate from the board and push out. Just be gentle and push as evenly as possible. Make sure the cable comes clear at the same time. Once the transformer is out, the PCB slides to the left and lifts out. I'm not sure if the top of the board is held by a rubber in the 8000 but if it is, this has to be lifted off first.
Have fun
Geoff
