The screws that hold the chassis in are under the bezel, to get to them remove the knobs and look around the shafts. Some of the shafts that have inverted pal nuts, Magnavox made a tool that slipped over the shaft and went into the nut to remove them, without the tool it can be tricky, but can be done.
The tool goes down into the nut instead of around it, in a pinch I've been able to get them off with a pair of duckbill pliers. When you get the pal nuts off then you can lift the bezel off, now look at both ends of the chassis on the same side as the knobs to the right of the dial, in the corners you should find two screws with 5/16 inch heads. Remove these screws and the chassis will lift out. If your set has controls on the left of the dial there maybe pal nuts there also that will have to be removed. As you are removing the chassis be careful that you don't catch the speaker selector switch they are easily broken.
