terminals. These are actually removable plugs. Pull all terminal plugs

support bracket from the transformer to the front plate until only a
few threads are left in the nuts.
- Remove the top inner screws on the front of the

only a few threads are left in the stand-offs.
- Carefully rotate the circuit boards away from the
