Addams Family: fusing the magnets to protect the playfield

Steps

• The three under-playfield magnets are driven by TIP36 transistors on a small board under the playfield; a shorted TIP36 locks its magnet on, which can get hot enough to burn the playfield.
• Fit an inline 2 A slow blow fuse in the feed to each magnet, three in all, under the playfield.
• A locked-on magnet then blows its fuse before it can scorch the wood.
